O-ball valve hole is a straight hole through the world

When the spool rotates, the change in area of ​​the orifice, characterized in
As follows.
1 flow characteristics similar features quick. Therefore, O-shaped ball valve is often used as a fiber-containing slurry or viscous fluid
Cut-off control valve, the operating temperature is not greater than 200 ° C, working pressure of not greater than 0.1 MPa.steam solenoid valves
Valve is symmetrical, the flow of fluid may optionally the spool rotational angle from 0 ° to 90 ° may be one-way rotation can also be bi-directional rotation.
Simple structure, easy maintenance, can be soft sealing, reliable sealing, leakage is very small, soft sealing O-ball valve (PTFE seat) up to bubble-tight.
4 adjustable than high. Typically, used in conjunction with the piston and actuator or electronic actuator, adjustable ratio of up to
100: l a 500:1.pneumatic hand valve
Expensive, much higher than ordinary ball valves.
V-shaped valve is in a V-shaped notch in the poppet valve, the flow characteristics of the shape of the incision and the control valve.
1.V the shaped ball incision allows the control valve flow characteristics of approximate equal percentage flow characteristic.
With the valve shaft rotation, V-shaped incision spin valve body, ball and valve seals in close contact, so you can achieve a good seal
Flow resistance is small, shear, is often used as a fibrous slurry or viscous fluid throttling control valve.
4. Flow capacity, flow capacity of up to 2 times with other control valve diameter.
5 adjustable ratio up to 200:1 to 300:1.
6. Applicable to operating temperature in a 40 to 450 ° C (2, working pressure of not greater than 6.4MPa occasions.high temperature solenoid valve
