Company Advantages
1. As an essential part of the final inspection, the labeling of Mech is verified by our QC team to ensure compliance with international clothing requirements. The particles in the fluid are not prone to stick to it due to its internal sheathing
2. The product marks a message: "From the beginning of packaging, we pay more attention to product users." This can motivate customers to buy. Produced with ductile iron material, it provides high strength
3. The product is able to hold acid food or liquid. It has been tested in a 4% concentration acetic acid tank to make sure the lead and cadmium precipitation is within the safe and healthy limits. It can be furnished with different types of internal trim and seals to accommodate varied service media

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 ASTM A536, 65-45-12
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.
