Automatic recycle valve

AUTOMATIC RECYCLE VALVE

Modern industrial equipment process request centrifugal pump are basically work under condition of variable flow, which needs set up automatic control devices in the process. However, when centrifugal pump under low load operation will appear overheating, serious noise, unstable and erosion which caused damage of pump. At this moment needs a kind of Automatic recirculation equipment, when pump under low load operation, through the bypass realize pump minimum flow backflow....

CONTROL VALVE

CONTROL VALVE

Control valve is made up of pneumatic multi spring diaphragm actuator and lower flow resistance straight single seat valve(sleeve). The single valve is connected directly with its guilding structure on the cap; with its corn is ram structure, which is smaller and lighter than normal single seat valve and its flux is bigger than normal sleeve valve. It is widely applied in industry process and automatic controlling system.....

BALL VALVE

BALL VALVE

Gate valves are used when a straight-line flow of fluid and minimum restric¬tion is desired. Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The gate is usually wedge shaped. When the valve is wide open, the gate is fully drawn up into the valve, leaving an opening for flow  .....

SAFETY VALVE

SAFETY VALVE

The Pressure Relief Valve is a valve mechanism for the automatic release of a gas from a boiler, Pressure Vessel, or other system when the pressure or temperature exceeds preset limits. It is part of a bigger set named Pressure Safety Valves (PSV) or Pressure Relief Valves (PRV). The other parts of the set are named Relief Valves, safety relief valves, pilot-operated safety relief valves, low pressure safety .....

CHECK VALVE

CHECK VALVE

Check Valve are generally used in drip irrigation emitters and irrigation sprinklers. Composition disc valves are ideal for applications involving gritty liquids. A clapper valve is a type of check valve which is used in fire fighting. Poppet check valves find use in “macro” flow applications. Arterial check valves are used in applications requiring centrifugal pumps to prevent retrograde flow along the arterial line......
