Sanitary Check Valves cod. VR

A solution for the prevent reverse flow and cross contamination.

DESCRIPTION

VR is a fully drainable sanitary in-line spring assisted check valve, which allows the flow into one direction only, preventing reverse flow and cross contamination. Versions suitable for horizontal or vertical installation.

All Pharmaceutical Certificates are available.

STANDARD DESIGN

The valve body is machined from solid round bar in stainless steel AISI 316L. It is made in two pieces assembled togheter with a standard clamp ring. The valve can be easily and quickly dismantled and reassembled without any tool.

A disc, sealed with two O-rings, guides the spring loaded shutter in the valve body seat.

HOW IT WORKS

The fluid pressure opens the valve. When the inlet pressure, generated by the fluid, exceeds the load of the spring then the shutter lifts and the valve opens. When the differential pressure across the valve drops the shutter returns to his seat

and the valve is closing.
