- Model 4M_BFLY - Butterfly_Valves

Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open. A butterfly valve is from a family of valves called quarter-turn valves.

Butterfly_Valves

Resilient-seated, butterfly valve for flange mounting to pipelines; concentric disc design; with replaceable liner. Suitable for use in cooling towers, waste-water applications, water treatment, water distribution, dams, gas main and service lines, pressure stations, gas storage tanks, power plants and gas pipelines industry.

Key Features

  • Integrally moulded seat liner on the body, which ensures excellent dimensional stability & guaranteed seat tightness.
  • Seat liner extending on to the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
  • Narrow land disc ensures perfect sealing with least operating torque requirements.
  • A fully universal body design ensures fitting of the valve between companion flanges of all popular standards (viz : ANSI, BS, DIN, JIS, IS etc.)
  • The notch disc & band lever ensures locking of the valve in 8 intermediate position in addition to close and open position. Hand lever can be locked through pad lock.
  • Body casting made of superior FG 260 grade cast iron to ensure additional strength.
  • Valve disc made of stainless steel / ductile cast iron which enable protection against possible water hammer or pressure surges.
  • A truly line size body bone to ensure maximum flow capacity with the lowest pressure drop.

  • Double Acting and Single Acting Actuators
  • On-Off and Proportionate Control
  • Resilient Seated Butterfly Valve with Electric Actuator

    • Single Phase and Three Phase Applications
    • On-Off and Modulating Duty Control

Triple_Offset_Butterfly_Valve

4Matic triple eccentric butterfly valves are suitable for both throtting and positive isolation applications. These valves are capable of bi-directional flow control, zero leakage, low fugitive emissions and stream-based applications (up to 550.c)

Due to the triple offset sealing system, the disc moves smoothly and free of friction at all points along the specially designed body seat & disc seal.

When the disc is closed, the seal ring (on the disc) energises the seat (on the body) there by proving a snug - tight high - performance fit.

The laminar seal is constructed with grafoil layers sandwiched between metal laminations. This resiliency of the seal flexes and energizes according to the compressive forces generated and allows for minor body deformations due to temprature fluctuations without the risk of jamming. This provides a uniform wedding effect and ensures bubble tight shut-off.

Damper_Butterfly_Valve

The butterfly or wafer damper can be a stack damper where sealing or tight shut-off is not all-important. This type is used as an isolating damper for flue-gas scrubbers. The butterfly damper is lightweight, simple, quickly actuated and often comparatively low in cost. In process work, oval shapes adapt to that shape of duct. Occasionally, a double-disc butterfly appears resembling a circular two-bladed louver damper.

The drive for a butterfly damper is also simple, needing only 90° of motion. The torque requirement can vary widely over damper life, if corrosion and thermal effects are severe. Hand levers, Gear boxes, Pneumatic Actuators or Electric actuators are used to actuate butterfly dampers.
