Matco-Norca's check valve
Matco-Norca’s UL-listed CVC ductile iron wafer-style check valve for use in commercial and industrial HVAC applications prevents reverse flow in water lines. Available in three sizes (4”, 6” and 8”), the check valve has a working temperature range of -10° C to 82° C (14° F to 179.6 ° F) at 175 psi. In addition to its wafer-style cast iron body, it features a spring-loaded double disc for improved dynamic operation and is fusion-bonded epoxy-coated to conform to AWWA C550. This valve’s extremely short face and compact design allows installation and service in tight spaces, and its spring-loaded double disc is soft-seated for perfect tightness even at low differential pressure.
