Statement

Gate valves serve to cut the medium flow in the piping system, widely used in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.

Features

◔ 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 MEIDE 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.

g******u

During the production of Mech , it is strictly tested, including lifetime test, heat and power breakdown test, and mechanical damage test.

q******d

The production of Mech includes overall three parts: the production of filament, the bulb, and the base, which is highly automated.

i******f

The production of Mech is strictly controlled with necessary electrostatic protection, from the production environment and equipment to operation staff.

z******o

Mech is manufactured utilizing a complete slate of necessary equipment including state-of-the-art photometric equipment and CNC machine.

m******o

The inspections of Mech are rigorously carried out by our professional QC team. These inspections include optical resolution, defect detection, structural integrity, etc.

z******u

The product does not accumulate too much heat. It has a radiator that can absorb the heat produced and then effectively dissipate the heat into the surrounding environment.
