Pneumatic two-piece internal thread ball valve,two-piece internal thread ball valve,ball valve

Fireproof structure design

The ISO5211 standard is directly installed with the actuator

Anti-static device between the ball core and the valve body

Explosion-proof design of the valve stem

The double-layer rubber rod packing complies with the valve stem leakage test of German TUV TA-LUFL

Double butterfly-shaped spring pieces automatically press the packing design

Allowable pressure difference: Less than 1.6Mpa of nominal pressure

[Valve Characteristics]

Optional limit switches, air filter pressure reducing valves, handwheel mechanisms and solenoid valves are available.

2. The aluminum alloy pistons made by precision die-casting process ensure the precise symmetry of the two pistons. Combined with high-quality O-rings and guide valves, it can provide a very high torque input and air pressure ratio. The double guide rails and piston design guarantee the constability of the output torque.

3. The piston guide belt adopts a large contact area, self-lubricating design and high-strength materials to ensure low friction. Its normal service life can reach 1 million times!

4. The valve body design features a reasonable structure. It can achieve bubble-level sealing, with a small opening and closing torque and a long service life.

5. An anti-static device is equipped between the valve body and the valve stem, and the valve stem is designed with an explosion-proof discharge device, which can be selected for various harsh environments. It has the advantages of beautiful shape and reliable quality.

function: Ventilation on, ventilation off, maintaining the current position in case of gas source failure

Single-purpose gas open type: open when gas is supplied, close when gas is cut off, and close when gas source failure occurs

Single-function gas shut-off type: shut-off when gas supply is interrupted, and shut-off when gas source failure occurs

Optional accessories: Reversing solenoid valve, limit switch, air filter pressure reducing valve, electrical positioner, handwheel mechanism, and the electrical part of the position-holding valve can be selected as explosion-proof

[Adapted Working Conditions]

Ball valves are important actuating mechanisms in industrial automation control systems. They can be remotely and centrally controlled to meet the needs of computer program control. Nowadays, in the fields of petrochemicals, gas equipment, nuclear industry, power equipment, environmental protection water treatment, HVAC, steel and metallurgy, and industry

It is widely used in industries such as industrial kilns, canning equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, biopharmaceuticals, food machinery, textile printing and dyeing, and papermaking.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition
