Project Description

The angle valve is a real trouble shooter solution for difficult conditions; it allows very large flow rates, it can operate from zero differential pressure and with high media temperatures, it operates at high viscosities and with dirty media, and it operates in EEx areas, merely by placing the pilot valve outside the area. Ideal Bell angle valves are operated by a pilot medium under pressure, usually compressed air but also oil, water or steam.

“* Features while select A type flow direction
Increase service life.
Prevent water impact when working medium is liquid.
Product with orifice size at Ø15, Ø20 or Ø25, it is necessary to keep working pressure under 0.3 MPa, otherwise double-acting actuators should be adopted.
Product with orifice size at Ø32 or Ø40, double-acting actuators should be Ø100.
Product with orifice size at Ø50, double-acting actuators should be Ø125.
* Features while select B type flow direction
Sealing property can be improved under B type flow direction while medium is steam or liquid. If the V shape sealing contact with working medium is too
long, and it will influence on service life. Apart from that, the anti-water impact does not exit when working medium is liquid.

“● Clean the pipes carefully from any residue, dribble or welding residue, to avoid any damage to the seal.
● To be installed as required, preferably with actuator in upright position.
● Connect the pipes according to the reference points (flow direction) found on the valve body. Only disassemble actuator if required by
● customer.
● Before taking the valve apart, depressurize the medium supply and piloted air supply from piping system.”
