Piston Valve

If you are looking for good quality piston valves, Well you have come to the right place. We manufacture Piston Valves. We hope we can help you find what you are searching.

  • Introduction:

KLU Model Piston Valve is a seat less and glandless valve using “resilient ring to Metallic SS piston” sealing principle to give as absolute leak tight system which is effective as well as reliable. The glandless design, ensuring no leakage, gives an edge over the regular valves where gland leakage is a common issue.

  • Efficiency & Reliability

The Sealing element is formed by two elastic valve rings enveloping a stainless steel piston. The upper valve ring seals to the outside, the lower ring seals across the port. Due to the large piston skirt the sealing effect is optimal. As the valve closes the piston removes impurities which the medium might contain from the inside of the lower valve ring. In this way, the valve reliably principle, damage to the sealing surface is precluded and tightness is guaranteed as a result.

  • Excellent control characteristics

The standard version of the piston valves is already very well suited for controlling the flow. Because the piston is guided by the upper and the lower valve ring vibration and instability in the pipe does not occur. Aira piston valves have proved to be excellent as by-pass control valves.

Through simple replacement of the piston and the lantern bush the valves can be retrofitted to act as a special precision control Valve.

Piston Valve

  • In line valve rings replacement

A newly installed piston valve does not require any maintenance for a long time after. However, the spindle should be regularly lubricated. if nevertheless, a valve ring wears out it can be replaced without problems while remaining in the line and, if assembly instruction is followed, It can be changed by in-house personnel and after replacement, the valve is as good as new.

  • The core of the Piston Valve : The valve rings

The high-quality valve is made of graphite laminate with tang metal sheet inserts made of stainless steel. The valve is absolute- asbestos and maintenance-free. The variable thermal expansions which occur under alternating thermal loads are completely compensated by valve rings, which were preserved in built-in condition.

  • Long term sealing even at highest demands

Media in the temperature range between -40 C & +400 C & at a pressure of up to 63 Bar. Can be reliably controlled.

  • Pressure Revealed Piston

In order to ensure convenient actuation at high differential pressures, the pistons are made of cast steel, whereof the sizes DN 65 to 200 are pressure revealed. The spindle is sealed with a gland and an additional valve ring provides the sealing between the body and the bonnet.

  • Advantage of Piston Valve

< Flameproof across ports & to atmosphere
< Maintenance free in the long run
< Environmentally safe and energy efficient
< Asbestos-free
< Easy to Install
< Inline replaceable valve rings
< Excellent Control Valve
