Valves Increase Reaction Time

Enerpac, an international market leader in high-pressure hydraulics, introduces new Venturi valves, improving the reaction speed of single-acting, spring and load return cylinders by up to three times.

Venturi valves create a vacuum-like effect in a pump system, drawing the oil from the cylinder and back to the pump’s reservoir at a much faster rate which increases the retraction speed of the plunger by up to three times. Venturi valves are available in both manual and electric configurations. Enerpac also offers retrofit kits for field installation on existing pumps for manual valves and solenoid operated valves. 

Venturi valves are an excellent choice for improving the efficiency of high tonnage cylinders. The retraction speed for spring return models can be slower than desired. Once the load is removed from a load return cylinder, the plunger will not fully retract without additional equipment to force the plunger back into the base of the cylinder.
