Product Description
Stainless steel gate valve has a rising stem and flanged connections on both ends. It has a flexible wedge, fully guided integrated seats, and bolted bonnet, and steel construction provides weld ability and greater rust resistance than iron. The rising stem moves up and down with the gate, providing a visual signal (when extended) that the valve is open. This stem design also prevent the stem threads from coming into contact with flow to avoid corrosion to extend valve life. This gate valve is full port for reduced friction; Its inner diameter is the same as the inner diameter of the pipe it connects to enable maximum operating efficiency.
The maximum working pressure is 285 pounds per square inch (psi), and the working temperature range is -20 to 100 degrees Fahrenheit. This valve has flanged end connections for bolting to compatible-sized pipe flanges. Mounted on top of the valve, a manually operated hand wheel activates the inside screw mechanism, which lifts and lowers the gate to start and stop the flow between the connected pipes.
This valve meets the following specifications for quality assurance: ANSI B16.34, B16.10, B16.5; API600, 598.
Gate valves control flow in a piping system by lifting a gate out of the path of steam, fluids, or gases. They are designed to block or permit flow, as the vibrations and force of flow repeatedly striking a partly lowered gate can damage the gate and seats.
To accommodate different flows and pressure requirements, gates come in four types: Solid wedge, flexible wedge, split wedge, and parallel disc (appropriate for high and low pressure applications). Hand wheels or levers activate the screw mechanism in the valve's bonnet, which comes in various designs, to open and close the gate. Union bonnets are preferable for building service piping, threaded-in (or screw-in) bonnets work well for lighter-duty usage, and bolted body-bonnet connections are used primarily in iron multi-turn valves. Most gate valves have either a rising stem, which moves up and down with the gate, or a non-rising stem, which remains fixed in place. When closed, the gate and its seats form tight planar sealing surfaces, ideal for linear liquid flow. Gate valves are used in air, gas, liquid, and steam applications.

Fangyuan Valve Group Co. Ltd, seated at Wuxing Industrial Zone, Oubei, Yongjia County, so called as "Pump & Valve Village of China", close to the national scenic spot Nanxijiang River to the east and facing the downtown of Wenzhou City to the south, and established in 1998 with the former as Zhejiang Fangyuan Valve Manufacturing Co. Ltd, has got a great achievement via hard work and continual going forth ahead and become a magnate of plate gate valve from an unknown small enterprise and leads the future of this industry. Fangyuan Valve Group Co. Ltd was derived from Zhejiang Fangyuan Valve Manufacturing Co. Ltd in 2005 and holds 5 stock subsidiaries, three production bases in Wenzhou, Shanghai and Lishui and a cast base in Lishui, a total registered capital up to 4, 000, 000 USD, a total land area 110000m2, over 600 staff members, 60 of which are technicians, a digital process center and more than 350 sets of various middle and large equipments and an annual output up to 12000 tons.
This Group comes as a key enterprise among the said"Pump & Valve Village of China"and a well known enterprise in the national valve industry and specializes in the production of plate gate valve, gas valve, electric station valve etc., with the development, design and invention patent know-how up to the advanced technical level of the world and the leading level of the nation and some of the products used to replace the imported ones. This Group has been accredited to ISO9001, API6A/6D, CE, AZ etc., won the first prize of scientific advance of Zhejiang Province and elected as a member of the first-grade supply network of China Petroleum, a member of China Petrochemical Resource Market, a member of No. 1 Energy Network, a member for supply of the national electric power system, an appointed production enterprise by Chemical Equipment General Corp., a Wenzhou high-tech enterprise, a start enterprise of Yongjia County, one of the 30 powerful enterprises among the said village and a banking credit AAA grade enterprise in the successive recent years. It holds a powerful strength in the technical, management and market etc. Respects and a notable superiority in the severe market competition.
