Parker's Fluid Control Division has announced the addition of the Sinclair Collins SCV-100 series of process control valves to its current offering. The series of diaphragm-operated process control valves includes models for numerous application requirements. The valves can handle steam and hot and cold liquids of temperatures between -40 and 450 degrees F, and can withstand pressures of up to 500 psi. They are available in two- and three-way, normally closed and normally open models. Also, cylinder-operated, manifold-mounted valves are available for applications in which manifolding multiple valves can simplify the process. Many also offer bubble-tight shut-off. The SCV-100 series, which comes in both hard- and soft-seated models, is constructed of durable cast bronze.
