Company Advantages
1. Thanks to the design of our professional team, the gas check valve has been widely popular in this industry. It will go through initial debugging tests before delivery for guaranteed quality
2. The soft fabrics, devoid of friction, assures a great deal of comfort to wearers, especially for people who are sensitive to the quality of fabrics. It is less prone to have scale build-up after long-term use
3. The product has a long service life. The quality of this product is assured based on its perfect design and fine craftsmanship, such as carving or embellishment. Its ability to keep pressure stability avoids vibration and noise
4. The product is safe to use. Because if the blower is suddenly cut off, the product will deflate slowly instead of coming down all at once. Its design ensures a good connection without leakage
5. This product has the advantages of weather protection, air retention, and mildew resistance. The materials used in it is degumming, and water resistant. It is used extensively in the automation, oil & gas industries

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.

◔ 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.

Note: For special material request other than standard specification, please indicate clearly on the inquiry or order list.
