Cautions for installation and maintenance for ball valve

6/7/2012

According to the construction, usually we can divide floating ball valve, trunnion ball valve, elastic ball valves and oil seal ball valve; if according to flow channel, it can be divided into straight-through ball valve, angle-through ball valve and three way ball valve. Three-way ball valve can be divided into T-shaped and L-shaped two kinds. According to the connection ends, it can be divided into the threaded connection ball valve, flange connection ball valve and welded ball valve three types.

The ball valve installation and maintenance should note the following:
1. to leave the space of rotary position for valve actuator.
2. it can not be used for throttling action.
3. It should be installed upright if the valves are actuated operated.

Nominal pressure: PN1.0-32.0MPa, ANSI CLASS 150-2500, JIS10-20K
Nominal diameter: DN6 ~ DN1400, NPS 1/4” ~ 56”
Connections: flange, butt welded, threaded, socket welding, etc.
Applicable Temperature: -196 ℃ ~ 540 ℃ Driving mode: Manual, worm gear, pneumatic, electric, hydraulic, pneumatic, electro-hydraulic linkage.
Body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304) CF3 (304L), CF8M (316), CF3M (316L), Ti. If we choose different materials, it can be separately applied to water, steam, oil, nitric acid, acetic acid, the oxidizing medium, urea and other media.

Valve Material : The facts should be considered in determining the correct valve material, likely the medium, temperature range, pressure range, possible atmospheric conditions and extraordinary stresses, safety standards and or piping code etc.
Valve Type : What is the control function of the valve? Gate valve, globe valve, check valve, ball valve, butterfly valve, plug valve etc.
