Product Details
A hydraulic cylinder and optional counterweight provide controlled opening and staged closing for pump-discharge and hydropower systems. Adjustable closing curves help reduce water hammer, while large bearings and rigid flanged construction handle demanding pipeline loads.

Body and trim materials, seat or sealing system, operator, coating and documentation can be customized to the actual medium, pressure, temperature and project specification. Manual, gearbox, pneumatic, hydraulic or electric operation is available where technically applicable. Dimensional inspection, shell and seat pressure testing, material certificates and application-specific inspection records can be provided with the order.
