Elasto-Valve Rubber Products (EVR), a manufacturer of rubber duckbill check valves, is drawing attention to the expanding role of duckbill valve technology in backflow prevention across wastewater, stormwater, and industrial piping systems. The company offers a comprehensive line of duckbill check valves engineered to provide reliable one-way flow control without the use of mechanical moving parts.

EVR rubber duckbill check valves function as passive non-return valves that open under forward pressure and close when flow reverses. Because they contain no hinges, springs, or mechanical components, they eliminate many of the failure points associated with traditional flap gate and check valve designs. This simplicity translates directly into reduced maintenance requirements and lower long-term operating costs for municipalities and industrial operators managing complex fluid conveyance systems.

Gary Waldick, Vice President of EVR Products, noted the growing demand for passive backflow prevention solutions. “We are seeing increased interest from engineers and facility managers who want dependable flow control without the maintenance burden that comes with mechanical alternatives,” Waldick said. “Duckbill valves offer that reliability in a straightforward, proven design.”

The EVR product line includes multiple duckbill valve configurations designed to address different installation requirements. The Slip-On Series CPO is built for direct mounting onto pipe ends, while the Flanged Series CPF accommodates bolted flange connections for more permanent installations. The Jacket Series CPJ provides an additional layer of protection for demanding environments, and the In-Line Flanged Series CPI allows integration within existing pipeline runs without requiring end-of-pipe placement.

For applications involving space constraints, the company manufactures an In-Line Series CPI-IN specifically designed for internal pipe mounting. This configuration protects the valve body while still allowing solids, sludge, and slurries to pass through unhindered. The flexible rubber construction of each valve adapts to varying flow conditions and permits passage of debris that would obstruct rigid mechanical check valves.

Backflow prevention remains a critical concern in municipal wastewater and stormwater infrastructure. Reverse flow events can introduce contamination into clean water systems, damage pumping equipment, and create public health hazards. Traditional swing check valves and flap gates require periodic inspection and replacement of internal components, adding operational costs over the life of the installation. Duckbill valves address these concerns through a design that requires no external power sources and operates silently under normal flow conditions.

Waldick emphasized the practical advantages of the technology for long-term infrastructure planning. “When a municipality installs a duckbill valve, they are choosing a solution that does not require scheduled part replacements or lubrication,” he said. “That translates into real savings over decades of service life, especially in remote or hard-to-access installations.”

The EVR CPO Series checkvalves, available in sizes up to DN2000, are specifically engineered for large-diameter wastewater and stormwater applications. These valves serve dual functions as both backflow prevention devices and odor control barriers, sealing against reverse airflow that can carry unpleasant gases back through piping networks into populated areas. This capability makes them particularly relevant for outfall structures, combined sewer systems, and tidal discharge points.

Elasto-Valve Rubber Products duckbill valve technology continues to gain recognition among civil and environmental engineers seeking low-maintenance alternatives to traditional mechanical check valves. The absence of moving parts means there are no components subject to fatigue, corrosion of metal hinges, or seizure from sediment accumulation. Each valve is constructed from durable rubber compounds selected to withstand the specific chemical and abrasive conditions of its intended application.

The company reports that its duckbill valves are currently deployed across a range of sectors including municipal wastewater treatment, industrial process water management, and stormwater conveyance. Installations range from small-diameter residential backflow prevention to large-scale outfall protection on major infrastructure projects. The valves accommodate varying head pressures and flow velocities while maintaining consistent sealing performance in the closed position.

EVR Products manufactures its full line of rubber duckbill check valves for distribution to engineering firms, municipalities, and industrial operators. Technical specifications, sizing guides, and configuration details for each valve series are available through the company.

JACKSON, MI – March 04, 2026 – PRESSADVANTAGE –

Nu-Ice Blasting, a U.S.-based, veteran-owned manufacturer of dry ice blasting equipment, has outlined new methodologies for heavy oil sludge and chemical residue removal in industrial settings. This approach completely eliminates the need for harsh chemical solvents such as acetone or isopropyl alcohol. Utilizing dry ice tank cleaning, the process leverages a non-abrasive industrial cleaning method to clear contaminants without collateral wear. The development directly addresses the broader industrial demand for in-place maintenance solutions that reduce operational downtime and labor requirements during scheduled equipment turnarounds.

The Commando® 40 PRO Dry Ice Blaster and similar models function by propelling solid carbon dioxide pellets through a pressurized air stream. Upon impact, the compressed air and solid CO₂ pellets dislodge accumulated surface contaminants. These systems are strictly manually operated by trained users within industrial environments. The intended users for this machinery include industrial facilities, dedicated maintenance teams, and specialized restoration professionals. The equipment features no automation and relies entirely on operator-controlled processes. It does not provide real-time optimization, requiring manual adjustments to accommodate varying surface conditions.

The Commando® 40 PRO incorporates specific mechanical features designed for precision and repeatability in controlled surface cleaning. Core system specifications include adjustable blast pressure regulators to accommodate different substrate requirements. The machinery utilizes controlled pellet feed systems, including a proprietary freezeless hopper design, to maintain consistent media delivery. Operators direct the output using specialized engineered hoses and nozzles built to withstand sustained thermal and pressure extremes. These technical components support targeted residue extraction while maintaining strict mechanical control over the entire cleaning radius.

Integrating this machinery into existing industrial cleaning workflows supports structured maintenance operations for large-scale containment units. The technology facilitates in-place cleaning processes, addressing the logistical burden associated with moving heavy machinery. Because the solid CO₂ sublimates upon impact, the procedure results in a reduced need for equipment disassembly prior to servicing. Applying this method to chemical vessel cleaning isolates the residue extraction phase within standard operational cycles. This framework supports established facility maintenance schedules by providing a predictable, operator-directed protocol for addressing difficult sludge accumulations.

The dry ice blasting equipment is applied across multiple sectors requiring stringent residue control. Applications include the maintenance of heavy manufacturing equipment and sanitization processes within food and beverage facilities. The systems are frequently utilized to process automotive components and delicate aerospace components. Operators also deploy the technology for clearing debris from active electrical systems. Additionally, the machinery serves a distinct role in fire and smoke restoration, providing a method for extracting surface soot and carbon deposits across various commercial and industrial structural materials.

The operational scope of the Commando® series is strictly bounded by manual input. The equipment possesses no autonomous operation capabilities and cannot perform any real-time decision-making. There is no independent execution of maintenance actions without direct operator control. Furthermore, the machinery contains no monitoring or facility management functions. All process variables must be actively managed by personnel present at the worksite.

Nu-Ice Blasting maintains its primary U.S.-based manufacturing operations in Jackson, Michigan. As a veteran-owned company, the organization relies on internal engineering and production capabilities to fabricate its Commando® equipment line. The manufacturing process centers on assembling precision mechanical components for heavy-duty industrial use. This infrastructure supports equipment distribution and standardizes parts availability for applications involving dry ice blasting chemical industry requirements and other specialized maintenance sectors.

Nu-Ice Blasting retains a continued focus on producing and supplying industrial dry ice blasting equipment for diverse operational needs.
