Control Valve


The OpGL globe control valve provides a superior  performance, while permitting easy, fast, inexpensive maintenance. Unlike diaphragm-operated control valves, the spring cylinder-actuated OpGL provides stiffness and  maintains high positioning accuracy controlled, and a faithful response. Since it handles up to 150 psi (10.3 Barg) supply air, it also has the thrust necessary to shut off against much higher fluid pressures. Most diaphragm actuators rely entirely on springs to close the valve. But with the OpGL control valve, the spring force, the supply air pressure and the fluid pressure itself, are combined to produce an exceptionally tight shutoff. Because of its self-aligning seat ring, shutoff is made easier to be achieved in the OpGL control valve. Most common maintenance problems with globe control valves can be traced to cage-guiding. The close metal-tometal contact between the cage and the plug often results in galling and sticking. That is why the OpGL is double-top stem guided thus completely avoiding contact between the plug and the seat retainer. The clamped-in seat and top entry trim permits easy, quick maintenance. Plus, with OpGL’s high degree of parts interchangeability, fewer inventory parts are needed and costs are therefore reduced. The actuator is also of a compact design, smaller, lighter and easier to handle than comparable diaphragm actuators. With Optimux’s quick-and-express manufacturing system, shorter deliveries at no extra costs are possible for the customer. OpGL.The simple, reliable, rugged and economic globe valve.
