Company Advantages
1. The design of Mech Valve os&y valve adopts an advanced software program. This software is able to calculate panel material quantities, manufacture measurements, and cost of the partition wall system. Produced with ductile iron material, it provides high strength
2. To customers, Shenzhen Mech Valve Trading Co., Ltd. aims to achieve meet their needs and create value. It can be used to control the flow of various types of fluids such as air, mud, oil, liquid metals, etc
3. Featuring flame spread resistance, this product meets the fire codes. Fire retardant has been added to its material during the production to enhance its anti-fire capacity. Its ability to keep pressure stability avoids vibration and noise
4. The product has satisfactory impact resistance. It can withstand the external mechanical forces such as pressing, grinding, or shock. The particles in the fluid are not prone to stick to it due to its internal sheathing

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.
