DVA35-DVG35 directional control valves are contemporary versions of our well-proven A35 units which have provided reliable control of fluid power for over 20 years. The VG models are cast from compacted graphite, a high strength iron alloy that allows the valve to be rated at 3500 psi. VA models are cast from grey iron and are rated at 2500 psi.

Several features are offered as standard on DVA35/DVG35 valves that contribute to their outstanding performance. Symmetrical timing makes change over from left-to-right hand operation simply a matter of removing the spool and re-inserting it in the opposite direction. Spool seals are fitted in counter bores for easier maintenance and smoother spool operation. These features, combined with the extensive range of available spool functions and options, make these valves among the most versatile.

Features

• Built-in, full flow relief valves
• Parallel and series circuits in one bank
• Manual, hydraulic, electric or pneumatic operation
• Sectional construction for maximum flexibility
• Spool changeover capability for right or left hand valve assemblies
• Low spool effort – improved metering

Outlet section
…..Standard – oil flow directed to the tank when spools are in the neutral and the A or B position
…..Power beyond – oil flow is directed to power beyond port when all spools are in the neutral position and return oil flow is directed to the tank port when the spools are in the A or B position.
