pilot solenoid operated spool valves
in Stainless Steel for use on gases.
• Hazardous area solenoids
• Closed centre
• ATEX, UL, CSA Approved
• EExd, NEMA 7&9
• Lightweight
Operating Medium
Filtered non-lubricated air,
inert gas, sweet (natural) gases.
Functional Symbols
Technical Data
Ports
• 1/4" NPT
(BSP option available)
Working Temperature
• Valve version -20ºC to +180ºC
(-4ºF to +356ºF)
• Solenoid version -20ºC to +65ºC
(-4ºF to +149ºF)
Low temperature version
• -50ºC (-58ºF ) (optional)
Working Pressure
• Single solenoid valve
3 to 12 bar (45 to 174 psi)
• Double solenoid valves
2 to 12 bar (30 to 174 psi)
Minimum Pilot Pressure
• At 6.3 bar (90 psi) body pressure
Pilot return 1.5 bar (22 psi)
Maximum Flow
• 6.3 bar (87 psi),
1 bar (14.5 psi) differential
• 3/2 valves - 1000 L/min (35.3 SCFM)
• 5/2 valves - 1200 L/min (42.4 SCFM)
Cv (Kv)
• 3/2 valves - 1.0 (15)
• 5/2 valves - 1.2 (17)
Instrument Signals
Valves with side mounted
solenoids can be supplied to
operate on instrument signals,
typically 0 to 1.5 bar (0 to 21 psi).
A separate supply to this pilot
solenoid is necessary. This supply
is 2 bar (30 psi) minimum for the
double pilot and 3 bar (45 psi)
minimum for the single pilot.
Construction Materials
• Stainless Steel AISI 316L
to NACE MR-0175 Body
• Stainless Steel AISI 316L
to NACE MR-01-75 Spool
• 316 Stainless Steel Spring
• Fluoroelastomer Seals
• Solenoid (refer to solenoid
specifications)

Ports
• 1/4" NPT

Working Temperature
• -20ºC to +180ºC (-4ºF to +356ºF)

• -50ºC (-58ºF ) (optional)
Working Pressure
(gases and liquids)
• 10 bar (145 psi) maximum
Function
PAD OPERATED, SPRING RETURN
WITH PILOT LATCH
If a pilot pressure of 1.5 to 10 bar (21 to 145 psi) is
present at pilot ports when the knob is pulled out,
the pilot pressure will hold the valve in the operated
position against the return spring. If the pilot
pressure falls to 0.5 bar (7 psi) or less, the valve
will be reset to its unoperated position. The valve
cannot be operated by pilot pressure alone, manual
operation must take place first.
PAD OPERATED, SPRING RETURN
WITH PILOT LATCH AND MANUAL
LATCH PIN
If a pilot pressure of 1.5 to 10 bar (21 to 145 psi) is
present at pilot ports when the knob is pulled out,
the pilot pressure will hold the valve in the operated
position against the return spring. If the pilot
pressure falls to 2 to 10 bar (29 to 145 psi) this will
simultaneously allow the latch to release whilst
holding the valve in the operated position. The valve
will reset to its unoperated position. The valve
cannot be operated by pilot pressure alone, manual
operation must take place first.
