Slab gate valves are usually used for the oil & gas pipe-lines.
Slab gate valve are manufactured with a full bore, slab gate, rising stem OS&Y and floating seats. Slab gate is a simple solid gate design, featuring metal-to-metal seal between gate and seats, to apply for the most severe service condition, including corrosive and abrasive fluid environments. A floating seat is designed to match the slab gate. A belleville spring and O-ring between each seat and body ensure a tight seal against the slab gate. The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high-pressure differential applications. Low-pressure sealing is accomplished with an o-ring that energizes the seat and minimizes corrosion and debris build up. Common trims are available.

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.
The products, approved by the nation and province early or late, have been elected as quality products of Zhejiang Province and well-known ones of Wenzhou. This Group follows the guide policy of"takeing people as the base, managing the company with laws, prospecting the enterprise with quality, continuing innovations"and makes the products well sold to all over the country and USA, Canada, the Middle East, Europe etc. World markets, greatly favored by the users therein. Therefore a solid basis has been made for the further open-up of the world market, for the making of Fangyuan brand, for the national industrial progression and for the great target to create a valve magnate of China and step forward to the 50 powerful valve companies of the world.
