FireLite PIB-V2 Post Indicator/Butterfly Valve Supervisory Switch


Our Price : $75.74

Product Code: PIB-V2


System Sensor’s PIBV2 and PIBV2A supervisory switches monitor the open position of post indicator and butterfly control valves. Robust construction. The PIBV2(A) consists of a rugged housing, intended for indoor and outdoor use. When installed with the actuator in the vertical position, the PIBV2(A) is NEMA 3R rated per UL.

Application flexibility. The PIBV2(A) features a flexible design that accommodates post indicator, butterfly, and many other types of wall post, recessed wall post and pressure reducing valves. The PIBV2(A)’s unique bi-directional actuator allows the unit to be installed in either rising or falling flag installations.

Simplified operation. Installation is made easier with the PIBV2(A)'s single-side conduit entrance. By providing a direct conduit pathway to the electrical source, right angle fittings are not required. Installation is further simplified by the PIBV2(A)'s adjustable length actuator, which eliminates the need for cutting the shaft.

Reliable performance. The PIBV2(A) is equipped with tamper resistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form-C) synchronized switches are enclosed in a durable terminal block to assure reliable performance.
