Trunnion ball valves | Shenli Instrument (certified) | Ball

Operation using a 1) is required to confirm before the operation piping and valves have been purged. 2) operation of the valve actuator input signal according to the size of the drive stem rotation is completed: the forward 1/4 turn (90 °), the valve is turned off. Rotate the 1/4 turn (90 °) welded ball valve, the valve opening. 3) When the actuator direction arrow parallel with the pipeline, the valve is turned on; indicator arrow with a vertical line, the valve is turned off the air supply valve instrument measuring pipeline system is an important part of the main shut-off valve and ball valve, Its function is turned on or off for the pipeline path available. Gas supply valve long life, tight structure, which has the following characteristics: 1. Butt-type valve, needle valve, forging body treatment to improve the heat resistance and strength of body, requiring the sealing valve tip does not rotate to ensure the seal tightness. Butt-type valve packing located below the external thread ball valve stem threads to isolate threads of medium trunnion ball valves, to improve the life of the valve. 2. All spool valves made of stainless steel and hardened to ensure the hardness of the valve, globe valve welded valves sit with carbide welding process to ensure that the valve temperature erosion-resistant, long service life. 3. shutoff valve flow path using low prices, the valve has good liquidity and switching performance. The ball runner for the straight-through, with good liquidity, especially viscous or crystallizing mediums clogging.
