Membrane Valves

Membrane Valves

MEMBRANE VALVES

Also known as a diaphragm valve, with guaranteed total tightness, with the possibility of being installed in any position, with easy maintenance: The three-piece design allows maintenance tasks to be carried out without removing the valve body from the pipeline.

  • It incorporates a lubrication system.
  • Steering wheel: comfortable grip and easy multi-turn operation.
  • Low torque shaft.
  • With little loss of load.

Butterfly Valves

BUTTERFLY VALVES

The butterfly valve is ¼ turn and controls the circulation by means of a circular disc, with the axis of its orifice at right angles to the direction of circulation.

Recommended for:

Service with full opening or full closing.
Strangled service.
For frequent actuation.
When positive cut-off is required for gases or liquids.
When only minimal trapped fluid is allowed in the pipe.
For low pressure drop across the valve.

Applications: General service, liquids, gases, semi-liquid pastes, liquids with suspended solids.

Ball Valves

Ball Valves

BALL VALVES

Ball valves are ¼ turn, in which a drilled ball rotates between resilient seats, which allows direct flow in the open position and cuts through when the ball is rotated 90 ° and closes the passage.

Recommended for:

  • For driving and cutting service, without choke.
  • When quick opening is required.
  • For moderate temperatures.
  • When you need minimal resistance to movement.

Applications: General service, high temperatures, semi-liquid pastes.

KNIFE VALVES

Manufactured in a single cast block with internal guides to guide the sash, with wedges that help the sash to close the body-seat, Unidirectional and Bidirectional, Wafer / Lug connection that allows high flow capacity and low pressure drop .

Its design in the form of a stepped transition prevents the accumulation of solids in the closure. Its design of the gate with rounded edges: prolongs the functional period of joints and packings.
