The wrench joint is made in cast iron and thanks to a synthetic painting is resistant to decay. It is the same as the last part of the extension operating device Art. 498. It’s a good alternative to the extension when the gate valve is near the ground, so the wedge is easily reachable by the operator with the wrench. The wrench joint fits to the stem by pressure. Using it the gate valve stem could be manipulated with any universal wrench.
