EFFAST check valves of PVC-U

EFFAST check valves made of PVC-U are divided into two types:

• spring check valves - they are equipped with a stainless steel spring. The body is made of a material that is safe for drinking water. Nominal pressure up to 16 bar.
• wafer type check valves suitable for installation between flanges. Dimensions comply with ISO/DIN and ANSI standards. The wafer type check valve has a swivel lobe in its design, which is adapted for a larger opening angle. Maximum pressure up to 16 bar (pressure decreases with increasing operating temperature). A perfect seal is guaranteed by the O-ring sealing system.
