DGMFN-H8 Pilot Operated Check Valves

DGMFN valves have double throttle/check valves in a sandwich plate design. They are used to limit main flow at one or two actuator ports. Two symmetrically arranged throttle/check valves limit flow (by means of adjustable throttle spools) in one direction and permit free return flow in the other direction.

Main flow limiting: The double throttle/check valve is fitted between the directional valve and the subplate to change the speed of an actuator (main flow limiting)

Features:

• Industry standard mounting, ISO 4401-8, NFPNA-T-3 .5.1-M-R-I, ANSI B 93.7 D08
• Sandwich plate design
• Limiting of main flow of two actuator ports
• Meter-in or meter-out control
