Applications
ZH4 sanitary check valve is used in stainless steel pipe systems to prevent backward flow of fluids.

Operating Principle
When the pressure of lower valve stem exceeds that of upper valve stem and spring force, ZH4 sanitary check valve is open. When the pressure of upper valve stem equals that of lower valve stem, ZH4 sanitary check valve is closed. Greater reverse pressure acting on the valve stem causes the valve to close.

ZH4 sanitary check valve has two configurations.

ZH4-1 sanitary check valve adopts clamp connection method. It is affordable and widely used in food industry.

ZH4-2 sanitary check valve consists of a thickened valve body and two flanges, which is easy to install and remove.
