Combined gas escape/supply valve is to be used in tank top
systems and other applications for easy gas flow, allowing
venting as well as pressurizing of vessel through the valve.
Partly closed for CIP liquid to be cleanable and self draining.
Valve housing: Stainless steel AISI 304 (SS 2333)
(AISI 316 on request)
Valve body: Polypropylene
Guide for spring: Polypropylene
Valve gasket: Nitrile O-ring, non-toxic foodgrade
materials. EPDM on request
Available in sizes: 1, 11⁄2, 2, 21⁄2, 3, NW80 and 4
Connection: The valve is produced with weld type
ends, but can be delivered with threaded
ends acc. to specifications, i.e. BSP, NW,
NPT, RJT, IDF, DS or clamp.
The valve housing consists of two parts held together by a
threaded connection. Inside there is a valve body and a
spring to keep the body in open position. The valve body is
drilled to ensure internal cleaning of the valve during CIP.

The valve is cleaned in-line during CIP of the vessel. The
liquid will close the valve but a special drilling of the valve
body ensures cleaning of its seat and the pipe connection
because a small amount of liquid flows through.
Depending on valve size this CIP flow is approx. 800-900 l/h.
The valve is typically positioned as an integrated part of the
gas/CIP-pipe at the top plate. It can be mounted at an angle
of maximum 45° to the ideal vertical position.
The valve should be checked for function with regular intervals.
The gasket to be changed every 2-3 years.
Low investment and maintenance costs
Maximum gas flow (both directions)
at max. 0.1 bar pressure drop
The internal polypropylene valve body is force opened by a
stainless steel spring, thus allowing full gas capacity through
the valve in both directions.
By introducing CIP flow against the spring force the internal
valve body will be moved to a closed position.
