CV - ABS Spring check valves
CV - ABS Spring check valves
The ABS check valves CV are designed for nominal pressure PN 15 at 20°C, with dimensions ranging from DN 15 to DN 50 (1/2” to 2”). The valve material is ABS, with seals available in EPDM or FKM. The spring is made of stainless steel, with an optional PTFE coating. The temperature range for operation is -40°C to 60°C. Coupling standards include solvent welded sockets according to BS standards.
Product Features
The ABS double union spring check valves are suitable for both vertical and horizontal installations. They are ideal for applications requiring precise closure and noiseless operation, particularly in low-temperature fluid transportation. The valves feature a stainless steel spring, with an option for PTFE coating, and seals available in EPDM or FKM.
Operating Conditions
The minimum opening pressure varies by size, with values such as 0.012 bar for DN 15 and 0.008 bar for DN 50. The maximum operating pressure is dependent on temperature, as indicated in the accompanying graph.
Components
The valve consists of several components including ABS nuts, sockets, and body, with O-rings available in EPDM or FKM. The spring is made of stainless steel or PTFE coated, and the plunger is also made of ABS.
Product Codes and Dimensions
The catalog provides specific product codes for EPDM and FKM versions, along with dimensions and weights for each valve size, ranging from 110g for DN 15 to 1000g for DN 50.
