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 (Double-

Pole 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.

Information

• 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).
