4S-V515A Compact Seal Butterfly Valves
Compact Seal Butterfly Valve excels over other conventional valves such as gate valve and globe valve in all aspects, especially in terms of light weight ( 1/ 3 -1/ 5 of conventional valves) , less number of component parts, no flange gaskets required and economical operation and maintenance costs.
The valve seats are constructed by a strong replaceable synthetic rubber, Fouress own seating mechanism of pressure-touch system offer a very low torque, tight shut-off with Ni leakage, compact actuator selection and long service life. Typically application of this valves are in pump rooms of large air-conditioning plants, as well as cooling towers; at heat exchanger inlet/ outlet, as a control butterfly valve; in ships, for engine room cooling water, ballast control; for smoke discharge and desulphurization in power plants or in denigration plants; in paper and pulp industry, oil refineries, steel and fertilizer plants; in sewage treatment plants; for water supply schemes; in air and gas lines etc.
