Function: It is in the exhaust state, allowing the gas with a pressure higher than the regulated pressure to be discharged from the relief port after pressure regulation, so as to ensure that the current pressure is stabilized within the regulated pressure range. If blocked, the pressurization will become the intake pressure, and there will be no regulation effect.
The working principle of the rotary valve (RZ000 series): The medium flows into the valve plate from the inlet side through the fixed orifice. The fixed orifice on the valve plate acts as a nozzle on the air chamber of cavity B of the valve seat. Through the pressure change, the force exerted by the valve seat on the valve plate, the force of the inflowing gas acting on the valve plate, and the closing force of the valve plate spring are balanced. At the same time, it acts on diaphragm A and balances with the acting force on the diaphragm to adjust the set pressure. Once the set pressure is too high, diaphragm A is activated, the distance between the valve seat and the valve disc increases, the pressure of the valve disc decreases, and the gap between the valve seat and the valve disc becomes larger and larger. The exhaust port opens to quickly discharge the pressurized gas on the inlet side. In this nozzle-flapper type guiding mechanism, the pressure deviation is detected, thus enabling precise pressure regulation.

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?
