Pilot operated breather valve is an advanced design that uses advanced technology to provide overpressure protection, reduce evaporation and exhaust volume, thereby reducing product losses and the cost of treating emissions. Pilot operated breathing valves are a part of high-performance breathing valve products, with quality and performance completely exceeding market standard valve performance. They have good applications in acid and ammonia solution tanks and have outstanding and unparalleled characteristics: high-performance sealed valve discs and advanced composite material PPS valve seats and cores.

Standard performance:

《1》 Design inspection standard API2000, high-performance sealing to reduce medium leakage in storage tanks;

《2》 When the overpressure is 10%, the full displacement can be achieved to ensure the discharge capacity; Advanced composite materials are used in the manufacturing of valve seats and cores, which have higher corrosiveness,

《3》 Resistance to liquid viscosity, maximum temperature (-45~260 ℃), and damage caused by valve disc freezing

Formed bonding;

《4》 The valve core and valve seat can be replaced on site without the need for special tools, which is convenient and simple;

Applicable scope:

Low pressure storage tank

The pilot operated breather valve can meet the tightness requirements of the valve seat according to environmental regulations: even when the operating pressure is close to the set pressure, such as when using a cover, it is still applicable.

Low temperature storage tank

The leakage relief valve of the low-temperature storage tank can cause unsafe icing. The sealed pilot breathing valve that can move quickly is the safest device known. The amplitude modulation valve * * * cannot be used at low temperatures.

natural gas

Some natural gas production equipment requires large capacity discharge capacity at low temperatures, and pilot control valves are an ideal choice for these needs. When the overflow valve is installed downstream of the pressure reducing valve, the regulating mode can prevent destructive interaction between the two valves.

Wind selection factory

Pilot operated breather valves can prevent accidental loss of gas when used in low-pressure processes or storage applications.

Hair dryer

Hair dryers used in conveying systems, wastewater treatment plants, and other areas often require precise discharge of pressure and vacuum. For pilot controlled overflow valves, including pressure valves and vacuum valves, this device is extremely suitable.
