Today is the most popular - a ball of pneumatic valve Pneumatic valve v-shaped ball

V pneumatic valve, alias: 'V' to cut off the pneumatic valve, v-shaped adjustment pneumatic ball valve; This ball belongs to fixed pneumatic ball valve pneumatic valve, is also a single pneumatic seat sealing ball valves, regulating performance is the best in the pneumatic ball valve, pneumatic seat between its v-shaped incision and metal shearing action, especially suitable for fiber, tiny solid particles and slurry medium pneumatic valve is the most popular a ball.
v-shaped ball pneumatic valve is a kind of pneumatic valve, it shut down a is half sphere has a V opening, v-shaped opening has a sharp edge, in the process of rotating sphere, wiping, between the closed to the media has a strong cutting force, the sphere of the v-shaped opening port to form a fan-shaped area with the pneumatic valve seat, can change the port area, in the process of rotary forming of medium precision adjustment, it is a kind of Angle of the adjustment of the rotary pneumatic valve, the same as the ordinary ball pneumatic valve seal performance, make it have a combination of regulation and switch two functions, equipped with pneumatic or electric actuators, widely used in industrial process control system.
material: stainless steel, cast steel, carbon steel, special dual phase steel, WCB, A,,, L, L, etc.
v-shaped ball pneumatic valve product features:
, pneumatic valve body integral structure of wafer and flange V type pneumatic valve pneumatic ball valve body is overall side mounted structure, structure, strong rigidity, not easy to cause deformation and leakage.
, self-lubricating bearings, self-lubricating bearings, up and down pneumatic valve body is equipped with pneumatic valve stem and the contact area is large, high bearing capacity, small friction coefficient, reduce torque of pneumatic valve.
, pneumatic valve seat can be according to the needs of medium and conditions, choose metal hard seal or PTFE soft seal: carbide surfacing metal hard seal pneumatic valve seat sealing surface and the ball surface hard chromium plated or spray welding, ion nitriding, such as hardening treatment, the service life of the sealing surface, enhance heat resistance increase; Soft PTFE sealing pneumatic seat or reinforced PTFE seat tightness good corrosion resistance, wide adaptation.
and economic practicality: pneumatic valve body light weight, small pneumatic valve rod torque, pneumatic or electric actuators with corresponding specification is small, compared with other types of regulating pneumatic valve, high cost performance.
medium adaptation range: because the v-shaped opening and the shear force between pneumatic valve seat, and pneumatic valve cavity flow in smooth round, make the medium is not easy to accumulate in the inner chamber, so it except for the liquid medium, more suitable for fiber and solid material medium system control.
and small flow precise control: by means of special v-shaped opening small pneumatic valve core processing, small Cv value precise control can be realized.
