• Improved retraction speed of single-acting, spring and load return cylinders by 3X
• Manual and electrically operated valve configurations
• Field Retrofit kits available for your existing inventory
• Excellent choice for improved efficiency when working with High Tonnage Cylinders

Challenge: Retraction Speed of Single-Acting High Tonnage Cylinders

• Spring Return Designs – Slower than Desired Retraction Speed
• Load Return Designs – once the load is removed, cylinders will not fully retract without additional equipment to force the plunger back into the base of the cylinder

Solution
Venturi valves create a vacuum-like effect on the system, drawing the oil from the cylinder back to the pump’s reservoir at much faster rate which increases the retraction speed of the plunger by up to three times.

Retrofit Kits
Retrofit kits are available to upgrade your current Enerpac pumps. For field installation on existing pumps we offer retrofit kits for pumps with the valve models below:

• Pumps with a VM33 or VM33L manual valve – order the VM33RVK Venturi Valve retrofit kit
• Pumps with a VE33 solenoid operated valve – order the VUV5 Venturi Valve retrofit kit

Upgrading a Pump with a Venturi Valve
For situations when you want to take advantage of our Venturi Technology, but your pump isn’t capable of being upgrade with a retrofit kit. You can replace your entire valve with a new VM33VAC or VE33VAC.
