2.5.2.1 Limit Switch
P/N 99456 (See Figure 2.5.2.1)
An optional explosion-proof limit switch may be placed on the manually
actuated valves to provide electronic conrmation that the valves are in proper
position. e limit switch has a NEMA 4, 4x, and 6 enclosure with one (1)
3/4 in (20 mm) NPT and one (1) 1/2 in (15 mm) conduit connection. e
switch is double pull double throw with contacts rated 10 Amps at 125/250
VAC and 0.5 Amp at 125 VDC.
2.5.3 Pilot Line Regulator
P/N 19170 (See Figure 2.5.3)
A polyamide and aluminum gas regulator is placed between
the discharge manifold and selector valves to reduce the
pressure into selector valve actuation ports. It has a 1/2 in (15
mm) FNPT inlet and outlet with a maximum inlet pressure
of 450 psig (31 bar) and an outlet range of 50 to 135 psig
(3.4 to 9.3 bar). It is normally set to 100 psi (6.89 bar). e
regulator has a standalone ambient temperature range of -20°
to 130°F (-29° to 54°C) and a Cv of 3.6. A pressure gauge
(0-160 psig P/N 19171) is attached to the regulator to allow
visual monitoring of outlet pressure. A 1 in (25 mm) regulator
is available (P/N 19513).
2.5.4 Discharge Relief Valve
P/N 19317 (See Figure 2.5.4)
A discharge relief valve must be installed in the discharge piping at
any point where pipe may be closed o between a lock-out valve and
a selector valve. Each relief valve has a 0.062 in² (40 mm²) orice area
and is set to open should line pressure exceed 450 psi (31.0 bar). Each
relief valve has a brass body with a stainless steel spring and a standalone
ambient temperature range of -320°F to 165°F (-196°C to 74°C).
