O-type pneumatic cut-off valve

　　Overview of Pneumatic O-Type Cut off Ball Valve

Pneumatic O-type cut-off ball valve - Pneumatic cut-off valve is a pneumatic right angle rotary cut-off valve. It is used in conjunction with solenoid valves and valve position switch boxes to achieve remote cut-off control. The O-type ball valve adopts an integral valve core and stem design to ensure seamless operation and prevent stem wear. Adopting a bidirectional metal hard sealing structure. Double directional sealing has small leakage and a wide temperature range. The gap between the valve core and the hard sealed valve seat has a large shear force and self-cleaning function when rotating. Especially suitable for controlling the on/off of suspensions and viscous media with fibrous and small solid particles. The pneumatic actuator adopts a curved arm conversion structure, which has the characteristics of large output torque, small volume, stability and reliability. The cylinder body adopts a mirror tube with smooth surface, oil-free lubrication, and long service life. Therefore, this product can be widely used in automation control systems of industrial sectors such as papermaking, petrochemicals, chemical engineering, metallurgy, electricity, environmental protection, petroleum, and light industry.

　　Characteristics of Pneumatic O-type Cut off Ball Valve

1. The O-type ball valve adopts a full bore design, and the flow resistance can be ignored.

2. The O-type ball valve adopts a bi-directional metal hard seal structure, with superior sealing performance, a wide temperature range, strong shear force, and rated leakage flow coefficient.

3. The valve core and stem of the O-type ball valve are cast as a whole, with no mechanical dead zone, and the stem never wears out. The service life is 5-10 times longer than that of ordinary ball valves.

4. The pneumatic actuator adopts a piston type cylinder and transmission shaft conversion structure, with large output torque and small volume precision. The actuator adopts a fully sealed waterproof design with high protection level.

The options for attachments can be selected based on different controls and requirements, including the following attachments:

Cut off accessories: single electric control solenoid valve, dual electric control solenoid valve, limit switch feedback device.

Adjustable accessories: electrical locator, pneumatic locator, electrical converter.

Air source processing accessories: air filter pressure reducing valve, air source processing triad.
