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.
