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.

Each production step of Mech is done via a rigorous process, from the mechanical process, the welding process, the spray painting process, and the fitting assembly. Its thickness can be customized based on requirements
Mech has been subjected to process screening experiments and tests such as heat aging, temperature cycle impact, and load aging. It is commonly installed in transformers, reactors, inductors, breakers, inverters, etc
The production of Mech is strictly controlled with necessary electrostatic protection, from the production environment and equipment to operation staff. This product has good mechanical strength and rigidity
Mech strictly undergoes a series of compatible testing. For example, its color rendering, light uniformity, and brightness are checked carefully. The product features high saturation flux density
The design of Mech is significantly optimized. It is designed with desirable optical properties such as color rendering, brightness, and optical efficiency. The product features high saturation flux density
The product is not easy to fracture. It has a strong performance in resisting extreme cold and extreme high temperature. The product features high saturation flux density
