Control pinch valves are designed for offering precise control over the flowing media, maximum durability, and require virtually no maintenance, especially in high pressure applications. With pinch valve high pressure, a rugged, heavy-duty pinching mechanism is involved in positioning the sleeve, the resultant flow of the media is quite accurate and measurable. Some of the features of high pressure control pinch valves include no seats for wear, no packing for maintenance, no need for expensive body alloys, and no fugitive emissions.
Control pinch valves are available in several heavy-duty sleeve designs. These include standard full port suitable for isolation applications with on/off functionality, cone, reduced port for control applications, and double wall for severe abrasive applications. The elastomer tubing, also known as sleeve, hose, bladder, or membrane, has the capability of closing on solids suspended in fluids.
The control pinch valves used for pinch valve high pressure are also available with several types of actuators. Electric or hydraulic actuators are used for automatic operations involving dealing with high pressure, while bevel gear actuators are suitable for manual operation. There are pneumatic actuators available in the market as well which are used in low pressure applications.
