Project Description

Butterfly Valve

CAMTECH Double Offset Butterfly Valve is design offers rugged reliability and extremely easy maintenance in the field. These valves are Bi-directional with zero leak features. Resilient seat design also can achieve low torque which is easy for operation. Camtech High Performance Valve delivers the highest quality and highest value available for meeting today’s demanding requirements of zero leak.
These valves are available in wafer style and lugged style. Few silent features are indicated as below,

With spherical disc, the geometry and construction of the seat results in smooth contact between the seat and the disc. This also results in reduced valve torque.
Blow out proof shaft design.
Reduced torque compared to other conventional valves.
Greatly reduced seat wear.
Bubble tight shut off over extended period of service.
Stellite hard face on the disc sealing face can be provided upon request.
Low emission packing set available for special service.
Live loading can be provided which maintain constant pressure on the gland.

CAMTECH Triple Offset Butterfly Valve design offers rugged reliability and extremely easy maintenance in the field. These valves are Bi-directional and with advanced design features of Triple eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a “tight”, bubble-free valve. These valves are well suited for operation in light vacuum to high pressure applications. The standard, non-rubbing, metal-to-metal sealing system is inherently fire safe by design. Triple offset butterfly valve can be used not only on-off but also regulating the flow. These valves are available in wafer, Lugged and Double flanged construction. Few silent features are indicated as below,

Suitable for High Temperature and High Pressure.
Blow out proof shaft design.
Reduced torque compared to other conventional valves.
Metal seated valve.
No Cavity. There is no cavity to allow build-up of solids.
Single piece shaft for safety is connected to the disc close to the bearings to absorb loads with taper pin.
Long shaft bearings center the shaft and the disc assembly with low operating torque.
Frictionless closure.
Low emission packing set available for special service.
Live loading can be provided which maintain constant pressure on the gland.
