Clark Solutions has introduced 8E Electric and 8P Pneumatic Series direct-mount ball valves with the lowest possible operating torque. The 8P Series ball valves require only a minimum of 80 PSI air supply. Clark Solutions’ new 8E and 8P Series ball valves are offered in a wide variety of models, from 1/4” to 4” brass or stainless steel, in 2-way or 3-way configurations, with T port, L port, full port, or standard port options, and with double acting actuators or spring return actuators.
8E and 8P Series direct-mount ball valves incorporate technologically advanced “O” ring back TFE seats to dramatically reduce operating torque. Viton O-rings are inserted into grooves formed and located on the backside of the TFE seat, preassembled as a unit and then assembled into the valves. The ball valve is assembled and tested with the O-rings exerting only a minimum amount of pressure on the TFE seats. The O-rings in turn seal on both the upstream and downstream side of the ball. Due to light force exerted, only a “single point” of each seat comes in contact with the ball.
