GENERAL:

ROSS’ new Series SV27 Sensing Valves Pilot Operated
Check, based upon the proven Series 27 valve family, combine
the tough, dirt tolerant characteristics of poppet technology with
sensing for actual internal position and state. Electrical feedback
is provided via a positively-driven, safety-rated DPST (Double­Pole Single-Throw) switch with both normally open (NO) and
normally closed (NC) contacts. The DPST switch is actuated
whenever the valve is not in the normal home position.

An optional visual pressure indicator (988A30) or pressure
switch kit (608A86) can be installed into the 1/8 NPT pressure
verifi cation port (PV) for verifi cation of pressure release.

FEATURES:

• Pressure controlled and solenoid pilot controlled versions.

• Poppet construction for near zero leakage & high dirt tolerance.

• Directly operated safety-rated force-guided positive-break
status switch (DPST).

• Holds a vertical load in the event of loss of air pressure
(and electrical power with solenoid pilot operated models).
