EMACO Gate valves serve to cut the medium flow in the fluid transmission system. It is widely use for fluid handling, flow control. It is designed to be fully opened or closed. On opening the gate valve, the flow path is enlarged in a highly non-linear manner with respect to percent of opening.EMACO Gate valves used for fire protection applications to maximum 80°C water temperature and rated working pressure is 300PSI (200PSI and 250PSI available upon request.)
Material : Ductile Iron EN-GJS-450-10 Body, bonnet, wedge, handwheel and operating nut are all produced in ductile iron material which provides guarantee for high strength and good corrosion resistance.
Triple O-ring Stem Seals : The lower O-ring isolates the stem thrust collar bearing area from the waterway. The upper two O-rings can easily be replaced in the line while the valve is under pressure in the open position.
Stainless Steel Stem, Brass Thrust Collar and Bronze Wedge Nut : This life-tested EMACO design has repeatedly proven its superior strength and abrasive resistance.
Fusion Bonded Epoxy Coating : Fusion bonded epoxy coating in accordance with ANSI/AWWA C550 for both interior and exterior surface which provides reliable corrosion resistance.
Long Service Life with Resilient Seat Cycling Test 1,000 times : The Valve has been subjected to 1,000 cycles of operation at a maximum rate of 6 cycles of operation per minute from fully closed to fully open and from fully open to fully closed positions under cycled hydrostatic pressure.
Products Type : OS & Y gate valve, Non rising stem Gate valve
End Connection : Flange by Flange, Grooved by Grooved, Grooved by flange, MJ by MJ, Flange by MJ available.
