Description

The SRV66HC all stainless steel sanitary pressure reducing valve

is a double seated, high capacity, spring loaded proportional

control valve which also benefits from having a quick release body

clamp ring. It is designed for hygienic applications in the food

processing, brewing/beverage and pharmaceutical industries. The

angle design allows for complete draining with no dead pockets

and is suitable for use in CIP and SIP systems. The valve does not

require an external pilot line.
