Ball Valve & Filter Ball Valve

Ball Valve

A ball valve is a rotational motion (quarter turn),quick rotating valve that uses a ball-shaped disk to stop or start or regulate fluid flow. The function of this valves, ball is same as of disk in globe valve. When the valve handle is turned to open the valve, the spherical ball rotates to a position where the hole through the ball is in-line with the valve body inlet and outlet of flow. When the valve is shut, the ball is rotated so that the hole is perpendicular to the flow openings of the valve body and the flow is stopped.

Application

Ball Valves are used for flow and pressure control and shut off for corrosive fluids, slurries, normal liquid and gases. They are used in the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses.

Salient Features: -

  • A ball valve is the least expensive of any valve arrangement
  • Ball valve offers low maintenance costs.
  • Ball valves are compact, require no lubrication, and give tight sealing with low torque

Filter ball Valve

The Filter ball is a corrosion resistant isolating ball valve containing an easily interchangeable strainer. This single valve in a compact space provides both isolation and easily maintainable protection of downstream plant and equipment.

Where strainers are required to be DN15 - DN50, a Filter ball combined quarter turn isolation valve and strainer should be used. Strainer is mounted within ball and is accessible for maintenance and cleaning when valve is isolated. No upstream and downstream isolation valves are required. Manufactured from Hot forged DZR, triple sealed blow out proof stem with 2 O-Rings and virgin PTFE packing gland.

Application

Suitable for heating, cooling, potable water and hot water services, compressed air, gas and oil. The Filterball and must always be in the fully open position to allow the strainer to operate correctly or fully closed during the strainer removal procedure.

Salient Features: -

  • A spindle fitted from the inside, this prevents extraction or bursting.
  • Interchangeable accessories and fittings such as the steel or aluminium levers and spindle extensions have been designed so that they can be substituted as required.
  • Double body connection seal: to guarantee absolute safety there is a double seal held with Loctite and a mechanical seal.
  • A PTFE seal and of two ‘O’ rings provide a triple safety stem seal for guaranteed protection.
  • Ball valve with integral filter easy to inspect and clean made of Corrosion
  • Resistant brass alloy CW602N, threaded ends.
  • Stem with triple safety (2-O-Rings, PTFE ring), fitted from inside to prevent tampering extraction or bursting.
  • Double tightening in the joint between body and end-connection.
  • Stuffing box movable.
  • Solid spheres are made using diamond tools and chromium plated to the required thickness.
  • Reversible handle.
  • Automatic cleaning device, with back flush feature.
