Function	PAD OPERATED, SPRING RETURNWITH PILOT LATCHIf a pilot pressure of 1.5 to 10 bar (21 to 145 psi) ispresent at pilot ports when the knob is pulled out,the pilot pressure will hold the valve in the operatedposition against the return spring. If the pilotpressure falls to 0.5 bar (7 psi) or less, the valvewill be reset to its unoperated position. The valvecannot be operated by pilot pressure alone, manualoperation must take place first.PAD OPERATED, SPRING RETURNWITH PILOT LATCH AND MANUALLATCH PINIf a pilot pressure of 1.5 to 10 bar (21 to 145 psi) ispresent at pilot ports when the knob is pulled out,the pilot pressure will hold the valve in the operatedposition against the return spring. If the pilotpressure falls to 2 to 10 bar (29 to 145 psi) this willsimultaneously allow the latch to release whilstholding the valve in the operated position. The valvewill reset to its unoperated position. The valvecannot be operated by pilot pressure alone, manualoperation must take place first.
