The VHEM range consists of a single basic valve body to which a manual actuating element can be attached in accordance with actual requirements. A large selection of toggle levers, push-buttons, hand levers and selector switches provides an ideal solution for every application, from mechanical sequence control to highly sensitive work piece inspection. The consistent design of the various actuating elements is striking: they’re distinguished by a uniform, robust style, they’re adjusted to the ergonomic needs of the user and clear and easy to operate.
