Stainless steel fixed pneumatic ball valve product characteristics and scope of use

fixed pneumatic ball valve, pneumatic valve is a new generation of high-performance ball, suitable for long distance pipeline and general industrial pipeline, its strength, security, and resistance to bad environment, special consideration when the design is suitable for all kinds of corrosive and non corrosive medium. Compared with the floating ball pneumatic valve, it works, pneumatic valve fluid pressure produced in the sphere of action before all passed to bearing, won't make a sphere to the mobile pneumatic valve seat, and pneumatic seat can't under too much pressure, so the fixed small torque of pneumatic valve, pneumatic ball seat deformation is small, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced springs in pneumatic seat components, since the tight characteristics, realize the upstream sealing. Each pneumatic valve has two pneumatic valve seat, each direction can be sealed, and therefore there is no flow restriction, installation is two-way. The pneumatic valve average installation.

there are two fixed pneumatic ball valve piece and three pieces of two kinds of pneumatic valve body structure, the flange bolting, seal enhanced ptfe inserted into the stainless steel ring, steel ring back no guarantee spring pneumatic seat close to the ball, keep the seal. Pneumatic valve stem up and down have PTFE bearing, reduce friction, easy operation, small at the bottom of the shaft adjustment, to ensure that the ball and seal it. Full size: pneumatic valve flow aperture is consistent with the pipeline diameter, so that the pipeline cleaning.

fixed pneumatic ball valve applicable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.

applicable temperature: - ~ ℃,

drive mode: manual, worm gear, pneumatic, electric, hydraulic, etc.

fixed pneumatic ball valve product features

and easy operation: sphere by the upper and lower bearing support, reducing friction, eliminating the due to the inlet pressure to promote a sphere with the great seal seal seat load caused by too much torque.

and reliable sealing performance: PTFE sheet material sealing ring is embedded in the stainless steel pneumatic seat, metal pneumatic seat end equipped with spring guarantee seal enough pre-tightening force, pneumatic valve sealing surface wear during operation, in the spring under the action of pneumatic valve to ensure good sealing performance.

, the structure of the fire prevention: to prevent because of heat or fire, make ptfe sealing ring burned, larger leakage occurs, and feeds the fire, in between the sphere and pneumatic seat set fire sealing ring, burned down in sealing ring, in under the action of spring force, the pneumatic seat ring is rapidly to the sphere, and form the metal to metal seal, have a certain degree of sealing effect. Fire test APlFA and APl standard requirements.

, automatic pressure release function: when medium pressure of the pneumatic valve lumen stagnation higher than spring pre] Force, pneumatic seat back out of the sphere to achieve the effect of pressure relief automatically, pneumatic seat after pressure relief automatically after

and discharge pipe: pneumatic valve body are set up and down drain away, L can check whether the pneumatic valve seat leakage, at work, or close the pneumatic valve is fully open, removing the midplane pressure, can directly replace the packing; Can discharge midplane retentate, reduce the pollution of the medium of pneumatic valve.

fixed pneumatic ball valve is widely used in food, medicine, petroleum, chemical, natural gas, iron and steel, environmental protection, paper transfer line cut or flow of the medium. Can also be injected the device with the corresponding detergent or lubricant was carried out on the sealing surface cleaning.
