PIBV2 and PIBV2A

Post Indicator/Butterfly Valve
Supervisory Switches

General

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.

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.

Engineering Specifications

Model shall be model number PIBV2(A) Post Indicator Butter­fly Valve supervisory switch as manufactured by System Sen­sor. PIBV2(A) shall be installed on each valve as designated
on the drawings and/or as specified herein. Switches shall be
mounted so as not to interfere with the normal operation of the
valve and shall be adjusted to operate within two revolutions
of the valve control or when the valve flag has moved no more
than one-fifth of the distance from its normal position. The
mechanism shall be contained in a weatherproof die cast
metal housing, which shall provide a side entrance for 1/2"
conduit and incorporate a 1/2" NPT nipple for attachment to
the valve body. A grounding provision is provided. The switch
assembly shall include two switches each with a rated capacity
of 10.0 A @ 125/250 VAC and 2.5 A @ 24 VDC. The cover
shall contain tamper-resistant screws for which a security
wrench will be provided with each switch. PIBV2
Underwriters Laboratories listed for indoor or outdoor use. The
PIBV2

(A)

shall be Factory Mutual, CSFM, and MEA approved.
