Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of the more common valves used in operations where valve speed is a necessity. WebAlso known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. They operate on compressed air to …

WebPilot-operated valves. Where accurate control of pressure or a large flow capacity is required, a pilot-operated pressure reducing valve can be used. Such a valve is shown schematically in Figure 7.3.4. A pilot-operated pressure reducing valve will usually be smaller than a direct acting valve of the same capacity. WebRecommended when instrument air or sweet and dry well gas is available, Cameron’s pneumatic diaphragm actuator is reliable and cost-effective. This actuator can be … WebThe Flomatic Model C000/CA000 Main Valve is a self-contained hydraulically operated, single diaphragm-actuated globe or angled body valve with no pilot controls. The valve has three major components: the body with a removable seat, the cover with bushing, and the diaphragm assembly. The diaphragm assembly is the only moving part.
