Bolted Bonnet, Parallel Side Gate Valve
CAMTECH Parallel Slide Gate valves are heavy duty, outside screw and yoke type, Bolted bonnet, rising stem and non-rising handwheel type. These split wedge concept is designed with the best feature of normal parallel‐slide valves: two separate gates that permit better inherent flexibility and freedom of each gate to align properly with its companion body seat. The straight through bore design assures minimum turbulence, erosion and resistance to flow. These valves have an excellent service history of successful performance in thousands of applications worldwide. These applications range from common manually operated component isolation valves in fossil‐fueled power plants through safety‐related motor operated valves (MOVs) in nuclear power plants. These valves are handwheel operated and gear operated depending upon the size.
