Tozen BFV-W are soft sealing butterfly valves for installation with flanges drilled in accordance with JIS, ANSI, BS, DIN, etc. Actuator mounting flanges conform to ISO 5211.To ensure tight shutoff for application in chemical processing plants, power plant, refineries, shipbuilding, pulp and paper mills, and HVAC applications. Tozen butterfly valves are specially designed to strengthen the seal tolerance between disc and liner.
Precision design ensures that an absolute shut off can be obtained for flow in either direction. Capable of meeting stringent specifications for various industries. Low head loss, low operating torque, superior corrosion resistance and light weight. Operator flange conforms to ISO 5211 adaptable for manual, electric and pneumatic actuators. Various parts, materials and flanged connections (wafer, lug and double flange type) are available.
