The Evacuate & Charge Coupler is designed for independent stem operation. The Operator manually clamps onto a PCU 250 Process Fitting then rotates the lever up/forward to open the fitting. When the lever is up/forward, this action locks the coupler onto the Process Fitting preventing the release of the coupler during the process. When this process is complete, the operator closes the flow passage & shutoff valve by rotating the lever into a down position. The coupler may then be removed from the Process Nipple. PCU, Inc will custom design couplers for your application.
