Automated vent and Drain Valves


Conval now offers Clampseal® and Camseal® automated vent and drain valves in 1/2" through 4" sizes that automate processes, improve efficiency, assure precise closing, extend product life, and reduce labor costs. These combinations eliminate excessive steam dumping, reduce treated water replacement, and allow for remote monitoring and control. Valves are repairable in-line, with no welds to remove and replace.   

Automated globe valves are available in angle, Y and T-pattern configurations and come standard with removable yokes for actuator mounting. Seats may be cut, ground and lapped. Disc can be turned or replaced, and lapped to the seat. Top entry ball valves feature a replaceable cartridge with new seat and ball that is factory-tested to assure tight shut-off. The valve has an indicator window and marked stem, to assure proper in-line ball alignment in open and closed positions. Integral ISO mounting flange is supplied standard.
