GENERAL:

ROSS’ new Series SV27 Sensing Valves, based upon the proven

Ser

ies 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. *For 3/4 and 1¼ bodies, the
DPST switch is actuated whenever the valve is not in the normal home
position. For size 2 body, the DPST switch is only actuated whenever
the valve IS 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:

• Solenoid pilot and pressure controlled versions

• Senses poppet position & state

• Electrical feedback via DPST switch (Double-Pole Single-Throw)

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

• Positive-break on 3/4 and 1¼ body valves

• Poppet construction for near zero leakage & high dirt tolerance

• Applications include Air Dump and Trapped-Pressure Release

Wiring Kits

These kits are available in lengths of 4 or 10 meters, with
a cord grip on each cable. The kits for SV27 solenoid
pilot controlled models come with 2 cables; one with
a 3-pin MINI connector for the solenoid and one with
a 5-pin M12 (Micro) connector for the sensing switch.
The kits for the pressure controlled models include only
one cable with a 5-pin M12 connector for the sensing
switch. (Note: Each cable has one connector.)
