The Hydraulic Shut-Off valve features a cast valve body with heavy wall sections for wear. The main body is designed with a round to square transition sized to equalize concrete velocity through the valve. Teflon valve packing seals are easily adjusted to control leakage and can be replaced without disassembling the valve. Maximum rated working pressure is 400ft. (122 meters) 28bar (400psi) vertical rise of concrete line. Consult factory for 6” valve specifications. The same features can be found on our manual shut-off valve V50SB & V60SB. The manual version uses a hand wheel and Acme threaded rod to achieve valve closure.
