Pressure reducing valve the new type pilot extra-huge membrane pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.Pilot Pressure Reduce Valve can realize the temperature control, upsteam pressure control, remote switch control. Super high sensitivity guide type diaphragm actuator provide a super high sensitivity regulate and flow control.
Free float steam trap is one of the most advanced traps since its ability of timely discharge of the condensed water in the pipelines and heating equipment. This trap has an extensive application in petroleum, chemical industry, light textile, printing, pharmacy, paper making, foods and mines.Continues discharging saturation condensed water without accumulation, and so get the maximum thermal efficiency.When steam pressure changes, the ball float can adjust the opening of valve seat without influence, and so it is stable.With automatic and manual releaser, and so its exhaust performance is good without airlock and working is smooth without noise.
Spring-loaded safety relief valve works through adjusting spring force to prevent medium pressure and realize sealing purpose. Under the condition of spring force greater than medium's normal pressure, valve disc is at the close state, when medium pressure exceeds the set pressure, the spring is compressed, and lead the disc sealing faces separated, the valve open automatically, and relief pressure; When medium pressure reduced to normal pressure, the valve disc go back to valve seat under the spring force, disc sealing faces and valve seat sealed again, the valves close automatically.

The inverted bucket is the most reliable steam trap operating principle known. The heart of its simple design is a unique leverage system that multiplies the force provided by the bucket to open the valve against pressure. inverted bucket steam traps open and close based on the difference in density between condensate and steam-the inverted bucket principle. They open and close gently, minimizing wear. This simple fact means that inverted buckets are subject to less wear than some other types of traps.Inverted Bucket Steam Traps belong to the family of mechanical traps. They operate on the difference in density between steam and water.

ANSI Y type Strainers are typically used in applications where the amount of solids to be removed is small, and where frequent clean-out is not required. They are most often installed in gaseous services such as steam, air, nitrogen, natural gas, etc. The compact, cylindrical shape of the Y type strainer is very strong and can readily accommodate the high pressures that are common in this type of service. Pressures up to 6000 psi are not unusual. When steam is being handled, high temperature can be an additional complicating factor. A steam pressure of 1500 psi will often be found at temperatures of 1000°F.

DIN Y type Strainers are typically used in applications where the amount of solids to be removed is small, and where frequent clean-out is not required. They are most often installed in gaseous services such as steam, air, nitrogen, natural gas, etc. The compact, cylindrical shape of the Y-strainer is very strong and can readily accommodate the high pressures that are common in this type of service. Pressures up to 6000 psi are not unusual. When steam is being handled, high temperature can be an additional complicating factor. A steam pressure of 1500 psi will often be found at temperatures of 1000°F.
DIN swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position. Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
