q341f/h/w/y api fixed ball valve purposes

q341f/h/w/y api fixed ball valve produced and sold by woci valve (shanghai) co., ltd, the valve body in the two valve seat parts along the vertical axis with the valve section is divided into three parts, the entire valve along the central axis around the stem symmetrical, it is mainly used in the pipeline to cut off, distribute and change the direction of medium flow. api american standard cast steel fixed ball valve its large pivot structure to ensure accurate ball center position under high pressure to ensure good valve performance; standard seat with spring structure, the valve seat to the ball, the api american standard steel fixed ball valve to ensure a good import and export of two-way sealing performance; api american standard fixed steel ball valve with its own discharge valve, the body cavity can be discharged to the outside; pivot blowing protection structure to prevent leakage effectively; low friction coefficient of bearings, making torque to a minimum, easy to open and close the valve; stem and body effective contact, the anti-static grounding device superior performance. with excellent performance, high reliability, wide range of uses, the price is reasonable and so on.


q341f/h/w/y api fixed ball valve structure characteristics

1, the manual part can be pressed steel handle or stainless steel casting handle. the handle is provided with a limit structure to set a limit position where the valve is opened and closed. when the valve is used on a key device, a lock hole is provided on the limit block to lock the switch position to avoid misoperation. there is a clear on and off indicator on the handle.


2, the stem with a182f (1cr13) overall forging and modulation, hardness hb220 ~ 250. stem by flat key or spline or square and the handle connection, versatility, easy disassembly. stem with anti-blowing structure.
3, the valve packing selection braided, flexible graphite seals or ptfe seals, making the stem in a certain lubrication conditions to achieve a reliable seal.
4,according to the need, the ball valve can be designed to anti-static structure, the ball and the stem, stem and valve body set between the conductive spring to avoid electrostatic ignition lit flammable substances, to ensure system security.
5, sealed in various forms. according to different conditions can choose soft seal, hard seal, fire valve seat and other structures; dn150 below the form of floating ball, below dn200 fixed ball form.
6, the ball valve seat can be set at the secondary seal structure, the valve seat and the stem part of the installation of grease injection valve, the emergency case can be temporarily sealed, and the valve stem can be lengthened according to need to be laid properly place.
