We occupy the leading position in electrically operated valve industry
This china valve supplier is suitable to the regulation which requests high precision during the flux of control liquid.
Electric single-seated, double-seatd and sleeve regulating valves are composed of ordinary DKZ series or imported electric actuator series and valve body which valve disc is single-seated type, double-seated type or sleeve typ.
It can achieve multiple accuracy control, flow characteristic equal percentage and linearity
automatic recirculation valve (pump protection valve) performance advantages:
1. Automatic recirculation control valve including recycling stream decompression facilities, high-pressure medium through the flow around several small diameter, a lot of energy, and reduce stress.
2. Pump protection valves have only very low flow recirculation, cooling pump, then pump during normal operation, there is no recycling, saving for a continuous recycling of the consumption of electricity and water.
3. Automatic recirculation control valve does not require electrical wiring, do not need two valves in series, one for the adjustment, the other for cutting. And the high-pressure systems are prone to cable and high speed flow to minimize erosion.
4. Pump protection valve with reasonable design, stable running, no noise, long life, etc., can completely replace the imported products.
5. Valve should be installed vertically.
Specifications
we make all kinds of pump protection valve, environment protect ,water, construction,factory,pharmaceutical,metallurgy,and so on.
submerged pump
FYH Submerged chemical pump
1.Summarize
FYH Submerged chemical pump is single suction chemical centrifugal pump, part of the pump is immersion in liquid. It can be activated without irrigation pumps or vacuum, and it is easy to use. Submerged chemical pumps are designed and improved by the our company, based on the traditional anti-corrosion liquid and the Swiss Sulzer companys advanced technique about similar products; They choose the unique structure of the impeller, and canceled other ordinary liquid pumps mechanical seals. Based on the medium particle size and of different characteristics, the impeller can be used closed or open type; enable the pump has merits of energy efficient, no leakage, and long life.
2.Usage
Widely used in petroleum, chemical, metallurgy, synthetic fiber, medicine, food, etc it can be used for transporting sewage treatment department and suspended particles of the corrosive liquid.
Minimum flow automatic pump recirculation valve system of feedwater pump of boiler in power plant
The most critical application in a Power Station is the Boiler Feed Pump Minimum Recirculation Service. A pump should have a minimum Flow through it to take care of the cooling requirements of the Pump.
Hence even if the Feed Water requirements are very low(due to low load conditions)the pump should handle a minimum flow. To ensure a mount of Flow has to be recirculated back to the Deaerator as the Flow requirements of the Boiler may not be sufficient to satisfy the minimum Recirculation requirements of the pump.
The parameters are obviously very detrimental for any valve to handle. The valve has to drop a pressure of 220-250 bar to 10 bar(Deaerator ppressure). Also it may be noted that the outlet conditions of the valve are near saturation, and hece the valve is very susceptible to high energy Cavitaion and Flashing.
The china choke valve applys to the severe fluid condition of high-preesure-drops between inlet and outlet side on the pipeline.
choke valve
1.meets JIS Japanese industrial standard,
2.featured by low torque and long life span.
api choke valve
The product meets JIS Japanese industrial standard, featured by low torque and long life span.
1.Reliability and economy of the contact valve plate: the valve plate has no friction with the seal ring. This tightly connected OKM seal construction realizes zero leaking. In addition, the minimum driving part of torque is designed smaller and lighter, reducing the cost.
2.Excellent wearable design: The contact seal construction limits the abrasion to the minimum. In addition, the bearing case used in the valve handle is wearable and is not stuck. The design of expanding the life span is everywhere.
3.Multi-closed construction prevent axial leakage: the first seal is between the valve plate and the seal ring and the second seal is between the shaft and the seal ring.
4.The main material of the valve is FCD450 to enhance the strength.

Butterfly valve may include a pressure-tight resilient seat and an angularly offset disc. Butterfly valve designs use a hard seat and an O-ring or piston ring around the disk to seal. Butterfly valve range in size from small to enormous, and are well suited for large flows of gases, liquids, or slurries, offer a number of advantages when used for the proper application.

The china butterfly valve structure featured by small flow resistance,strong tongness and less pressure loss,which reduces friction of the sealing ring,providing the valve a long service life.”T” structure of the disc sealing ring. The sealing pair is linear sealing. The disc sealing ring is easy to replace and maintain.
The end of the diaphragm valve is double-metal stopping shims of high efficiency,which can be installed vertically or horizontally with convenience. It is recommended that to use the valve in one way but in the case of the revers sealing is not important,using in double way is permitted. As the valve is fully closed,the leakage in sealing testing can be lowered to zero. By replacing materials of disc sealing ring,o-ring,disc,body and stem, this valve can be used for various medium and temperature.
