Spring band wrench fully open safety valve
Features:The product can be used in petroleum, chemical and other industries.
Spring belt wrench slightly open safety valve
Model:A47H, A47Y PN16~PN40
Features:The product can be used as overvoltage protection device when working temperature is less than 350 degree C.
Hydraulic safety valve
Features:Hydraulic safety valve is also called the Y type hydraulic pressure relief valve. Y type hydraulic pressure relief valve which is installed on top of the tank, an important attachment to protect the safety of oil tank
Blast wave relief valve
Features:FH49H type explosion-proof safety valve is a kind of both can eliminate water hammer shock wave can stop the water hammer shock wave water safety valve.
WA41C bellows balance type micro spring safety valve
Features:Bellows valve is suitable for the working temperature of 300 ℃ or less medium such as air, steam, liquefied petroleum gas (LPG) of equipment and piping, as the overpressure protection device. When equipment and pressure exceeds allowable values in the pipeline, the valve automatically opens, then the amount of emissions; When pressure is reduced to the specified value, the valve automatically shut down, guarantee the safe operation of the equipment. They are widely used in electric power, metallurgy, petroleum, chemical industry, etc.
Steam safety valve
Features:The relief valve acts as a safety guard in the system. When the system pressure exceeds the set value, the safety valve open, part of the system in the gas / fluid / pipeline into the atmosphere, the system pressure does not exceed the allowable value, thus ensuring the system is not an accident due to excessive pressure.
Balance the pilot operated relief valve
Features:Summary: A46 pilot operated relief valve adopts open pilot valve structure, consists of a main valve and a pilot valve, suitable for working pressure close to the setting of the workplace. Product features: basic design specification: test: GB/T 12243 GB/T 12242 product specifications and product model: A46 size range: DN25 ~ DN200 pressure rating: 1.6 ~ 16.0 MPa shell material: carbon steel, stainless steel, alloy steel applicable medium: gas, liquid operating mode: automatic design features Soft seal seat to ensure good sealing allow working pressure before and after the opening close to the setting pressure smaller overpressure can achieve fully open movement performance and open height is not affected by back pressure opening and closing pressure general adjustable
Spring micro opening external thread safety valve
Features:A21F, A21H-C spring micro open type safety valve screw type suitable for working temperature are less than 200 of the air, ammonia, oil gas and other media of the equipment or pipeline. A21W-P, R type spring Weiqi thread safety valve for temperature are less than 200 with corrosive gas or liquid equipment or pipeline, as the overpressure protection device. KA21Y type spring Weiqi thread safety valve for temperature are less than 100 of liquid petroleum gas.
Superheater safety valve
Features:Safety valve (Safety Valve, also known as the pressure relief valve Relief Valve) is based on the pressure system working pressure (temperature) automatic opening and closing, usually installed in the closed system of the safety valve on the pipeline safety protection system or preparation. When the equipment or pipeline pressure or temperature exceeds the safety valve set pressure, automatic opening pressure relief or cooling, ensure equipment and medium pressure pipelines (temperature) at set pressure (temperature) under the protection of equipment and piping work, prevent accidents, reduce the loss.
High-performance balance pilot operated relief valve
Features:The relief valve pilot valve is used to sense the accused of pressure signal and the signal is given, the pressure is lower than before when the relief valve setting pressure, pilot valve and main valve is closed without leakage. The supply pipe, the main valve through the pilot valve on top of a pilot valve seat and the valve core, due to the top of the valve core is greater than (seat) at the bottom of the valve core has a large force to keep down, before the valve pressure is closed more closely, the closer the setting that the sealing structure in the main valve dual qualitative hard and soft sealing side, the net sealing force increases with pipe pressure increases and close to the set point. When pressure before the valve meet or exceed the whole east, pilot valve open, open the main valve quickly, medium emissions; When pressure before the valve back to setting, pilot valve closed, the main valve ?
