ANSI Gate Valve

specifications of the ANSI Gate Valve

ANSI Gate Valve (cast steel) includes cast-steel gate valve and forged steel gate valve which is designed and manufactured according to ANSI B16.34.It can be used for different pressure because of two type wedge-solid wedge and flexible wedge.Gate valves have back seal which is weld with stainless steel,therefore, it has perfect sealing. With convinient maintainance, it is widely applied to petroleum,chemistry,water treatment industries.

It has four unique features: (1)"H" type wedge. Gate valve has "H" type, flexible single wedge which can compensate the distortion of body. And it has reliable sealing and prevent wedge against difficult operation because of overload, which is suitable to steam and other high temperature medium; (2)full port design. It has full port and is convenient to clear pipeline; (3)changeable seat. Seat and body is connected with thread which makes it possible for the seat to be dismantled and changed and brings convenienience to maintenance; (4) Precise design. The design of the body and bonnet based on precise calculation. body and bonnet have high strength, rigid and flow ability.

There are some technical specifications about it.(1)Nominal diameter is 2"-24".(2)applicable temperature is -29℃～425℃（steel）-40℃～-550℃ (stainless steel).(3) nominal pressure is 150Lb 300Lb 600Lb 900Lb 1500Lb.(4) applicable Medium is water 、gas、oil、and other causticity medium.

At last, there are also some application standards about it.(1)manufacture standard : ANSI B16.34.(2)face to face dimension: ANSI B 16.10.(3)flange dimension: ANSI B 16.5.MSS-SP-44.(4) test: API 598. API 6D.

ANSI Gate Valve

A ANSI gate valve should reach the standards that settled by ANSI.

ANSI is short for American National Standards Institute,which oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide.

ANSI itself does not develop standards, the Institute oversees the development and use of standards by accrediting the procedures of standards developing organizations. ANSI accreditation signifies that the procedures used by standards developing organizations meet the Institute's requirements for openness, balance, consensus, and due process.ANSI also designates specific standards as American National Standards, or ANS, when the Institute determines that the standards were developed in an environment that is equitable, accessible and responsive to the requirements of various stakeholders.
