We offer in-house tooling and rapid production to meet custom requirements with minimal lead time.
Our seals provide high sealing efficiency with low torque operation and are available in sizes ranging from 25 mm to 950 mm.
Depending on application needs, materials include Natural Rubber, EPDM, Nitrile, Neoprene, Silicone, FKM, and Viton.
A butterfly valve is a shut-off valve with a relatively simple construction. In closed position, the disc blocks the valve bore while in open position, the disc is turned to allow flow. A quarter turn takes the valve from fully open to fully closed position, or opposite, and thus the butterfly valve allows for quick opening and closure.
Butterfly valves can be used for a broad range of applications within water supply, wastewater treatment, fire protection and gas supply, in the chemical and oil industries, in fuel handling systems, power generation etc. Some of the advantages for this type of valve are the simple construction not taking up too much space, and the light weight and lower cost compared to other valve designs.
The valves can be operated by handles, gears or actuators according to any specific need.
