BKH-SAE Series Flange Ball Valve Hydraulic Indsutry Valve
Flanged ball valves are widely used in industrial pipelines requiring high tightness, frequent operation and control of fluid direction, especially in petroleum, natural gas, chemical industry, power generation, heat supply, urban construction industry and other fields. The flange connection mode provides reliable and removable assembly and maintenance interface, while the ball structure ensures good tightness and operation reliability, which can be used to open and close the pipeline.
application area
Petroleum and natural gas industry: used for long-distance pipelines, as a control device for opening and closing, and can achieve zero leakage.
Chemical industry: applicable to transmission of various media, especially under the condition of impurities and chemicals.
Power generation and heating industry: in the field of long-distance pipelines, it is used as a control device and improves the accuracy of thermal energy measurement.
Urban infrastructure construction (urban construction): applied to the construction and maintenance of urban pipe network.
Water treatment industry: places used to control liquid level, such as reservoir and water tank.
Paper industry: as a fluid control component, it is used in the automatic control system of paper making process.
Application advantages
Zero leakage and energy conservation: some flanged ball valves (such as all-welded flanged ball valves) can realize zero leakage, reduce energy loss and improve energy conservation.
High reliability and long service life: stable structure, good sealing, no unreliable castings, and long-term operation under the condition of impurities.
Easy installation and maintenance: flange connection provides removable interface, which is convenient for assembly, disassembly and maintenance of piping system.
Multiple control functions: it can not only be used as a shut-off valve, but also as a control valve to meet different process requirements.
Suitable for complex environment: capable of handling fluids containing impurities and chemicals, and stable operation under high pressure and high temperature

Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .
Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ?
A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,Siemens,Rosemount,Marsh ,Endress+Hauser etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
