Hydraulic Prevent Shut-Off Valves

Production floor environments often cause difficulties with identifying and operating valves for mechanical applications. Shutting off the return valve before the pressure valve on a hydraulic system commonly leads to leaking seals on hydraulic components.

The Solution 

Designed specifically for the production floor, our Hydraulic Prevent Series Valves only allow the “supply” side to be shut before the “return” side – preventing unwanted pressure on hydraulic motor seals.

The standard Washdown Proof Flow Control addresses the issues caused by corrosive wash-down chemicals or breading dust on exposed stem threads, by sealing the stem in a stainless steel adjusting cover and filling the void with a food grade grease.

The integral singular Red locking device allows both valves to be Safely Locked Out in the “Off/Closed” position.
