4S-V515A & 4S-V16 ( 16 Bar) Compact Seal Butterfly Valves

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. For Detailed Specifications and Dimensions Download Brochure Material of Construction APPLICABLE FLANGES BS: 4504 PN 10, ANSI 125ib/ 150lb MAX.

CF8 / CF8M) 4S-V16 ( 16 bar) Butterfly Valves Introducing the Fouress 4S-V16 High Pressure Compact Seal butterfly Valve. Combining versatility with high performance and ease of operation, the 4S-V16 brings in modern design advantages to general purpose valves. The 4S-V16 is designed to take higher pressure, up to 16 bar. With a soft seated wafer construction and a unique sat sealing design, the 4S-V16 scores over conventional gate valves in every aspect. Its light weight and simplicity of construction ensures economy in operation and maintenance. The 4S-V16 compact seal construction and flexibility of body, seat and disc materials render it suitable for a wide range of fluids and gases; water, air, town gas, oils ( expect aromatic hydrocarbons) , dilute acids for high pressure applications in air conditioning & refrigeration, ship building, fire fighting systems, water supply, sanitation lines, hotels, high rise buildings, water distribution tankers and other general fluid isolation and control applications.
