Multistage Pressure Reduction Valve
BEIER Control Valve Company have Cage type multi-hole trim low-noise control valve, They are applicable in a wide required scope of pressure reduction and reducing noise services. Multistage pressure reduction type Trim have a multistage pressure reduction structure with continuing improvement and perfect mature. Labyrinth type Multistage pressure reduction control valve is mature product for adopted the international advanced technology and manufacturing technics.it guaranteed to be effective and reliable working in a special scope of liquid services as well as steam/gas services.

 

Technology introduction
Side manual operation device
GYL series control valve could be collocated with handwheel device,when system is shut down or maintaining,or Air or Actuator is failure,could handle control valve by manual operation device,our new structure manual operation device have perfect Operability and the convenience of disassembly.

BEIER multistage pressure reduction trim, have multiple discs (which have many special designed narrow variational ports,ports is based on pressure reduction progression’s different amount corner,compress and outspread) superposed to be a multistage pressure reduction cage.while fluid is flowing,have to pass by multi-times, have a progressive pressure reduction process.By BEIER multistage pressure reduction trim is fitted with plug,made fluid throttled and passed by most devious variational ports,then getting one stage pressure reduction when fluid passed by every corner,in this process wasting the kinetic energy of fluid,reducing the flow velocity of fluid,getting multistage pressure reduction.to fluid of gas,by muli-times convection expand,reducing the flow velocity of fluid,reducing the intensity of noise,reducing the erosion that fluid actioned to trim,to fluid of liquid,every pressure reduction is no more than the saturated steam pressure.to avoid cavitation erosion and flash vaporization,reducing the origin of noise.
The structure of BEIER multistage pressure reduction trim is based on principle of progressive pressure reduction,according to specific spot technics conditions.by different combination, collocated of disc,getting different adjusting purpose.in selection of valve type please take attention to technics conditions as bellows:the kind of media,flow,density,operating pressure,pressure drops,operating temperature.by technics condition to decide labyrinth type multistage pressure reduction control valve’s Cv, progression of pressure reduction,flow characteristic, nominal pressure etc.

At present, labyrinth type multistage pressure reduction technology is the best solution to problem of controlling and operating in severe technics condition.it’s more advanced than traditional cage type multi-hole trim,and getting more multistage pressure reduction effect. To use labyrinth type multistage pressure reduction control valve have remarkable effect as bellows:

1.  Dependable reach the condition of high-temperature,high-pressure and high pressure drops,media that high velocity of flow.
2.  Reach the condition of noise limitation,be effective on noise control.
3.  Improve the high vibration performance of control valve.
4.  Perfect long service-life of trim and control valve.
5.  Dispelling the equipment’s damage from cavitation,noise and vibration.
6. Reducing the shut-down time of equipment,reducing maintenance,and the cost of maintenance,increasing factory’s producing capacity.

The application of BEIER labyrinth type multistage pressure reduction control valve as bellows(electric power industry,pertro industry,natural gas industry etc):

• High pressure steam regulating and emptying
• Compressor’s recirculation and Anti-surge
• Host start-up of feed-water pump,host booster pump’s recirculation
• Condensate booster pump’s recirculation
• Boiler Feed Pump’s least flow recirculation
• Ethylene and low pressure,heavy oil low pressure
• Steam turbine by-pass and start regulation
• Boiler ‘s Feed-water regulation
• High-pressure cooling water injection regulation
• Expansion turbine by-pass regulation
• High pressure air current flow regulation
