Cast Steel Stainless Steel Bellow Sealed Gate Valve For Thermic Oil Use
Product introduction:
Bellow seal gate valves has an adjustable gate (a flat or wedge-shaped barrier) that controls the passage of fluid through the valve. The metal part that encircles the valve stem is called the bellows, and it is pliable and accordion-like. It is frequently constructed from substances like stainless steel and is intended to endure high pressures and temperatures. Even in challenging situations, the bellows functions as a dynamic seal to stop leaking along the valve stem. In situations involving poisonous or hazardous fluids, the bellows seal design offers outstanding sealing qualities. To fit a variety of applications, these valves come in a variety of materials. Materials are selected based on variables including fluid type, temperature, and pressure conditions. These valves are frequently employed in sectors including chemical plants, refineries, pharmaceutical production, and power generation facilities where fluid loss might have detrimental effects. According to the particular application and control needs, these valves can be operated manually, pneumatically, or electronically.
