Slab Gate valve
The slab gate valve is also called flat gate valve used of the floating valve seat and O-ring sealing, so that import and export of two-way valve seal plate; The headstock and the structure is only an ordinary valve torque 1/2, to achieve easily open the valve clearance. Plate valve for Class150-900/PN1.0-16.0MPa, work temperature -29-121 DEGREE C. Medium is oil, gas, water, oil and other medium, used for cut-off the media.
Pressure: 150LB-2500LB
Size: DN15-DN1200
Design Std: API, DIN, BS, GB, JIS
Product Material: CAST-IRON, ASTM A216 WCB, A351 CF8, A351 CF8M, A105, A410
Slab gate valve is suitable for natural gas, petroleum, chemical industry, environmental protection, city pipeline, the gas pipeline conveying pipeline, such as steam vent system and the storage device, used for opening and closing device. Also it's suitable for natural gas exploration and purification of long distance pipeline.
Characteristics of flat gate valve:
1 Valve seat sealing structure shall be flexible with pretension, while sealing. It always seals face to face between valve seat and seal materials.
2 Valve seat with self-cleaning function, which directly in flushing opening or air flow is not affected by the closing process. Seat shall be lubricated, nor wear materials.
3 The faults in valve actuator will not affect other parts of the valve, and repair or replacement without removing the valve in the case.
(1) yoke sleeve: Aluminum Bronze yoke sleeve configuration needle thrust bearing, minimizes operating torque.
(2)the stem length of thread until the bracket; The pin and spot welding; Stability.
(3) the pressure seal: Has the advantages of simple structure, configuration of sub ring and silver plated low carbon steel washers, helps in removing and achieve the best bonnet seal.
(4) the seat ring: Welded seat rings are perpendicular to the flow channel, easy to maintain.
(5) implementing agencies: The valve can be electric, hydraulic or pneumatic actuator. DN300 the following configuration standards for hand wheel, DN350 above configuration helical gear operating mechanism.
(6) the yoke: Completely fabricated yoke by seismic testing, ease of maintenance and installation of the implementing agencies.
(7) gland: Two piece, self-adjusting gland, to avoid being ejected.
(8) integral backseat: Hard, the longest service life.
(9) the valve: The valve spring load to adjust, reduce actuator torque requirements.
(10) the overall stop: The whole cast bracket stop device, positioning the valve assembly of the bracket, making the seat more stable and reliable.
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.
