ZSHVType V pneumatic regulating ball valve PN16 ～ pn110 is a kind of rotary regulating ball valve, which is the executive unit of pneumatic unit combination instrument. It is generally used in combination with electric valve positioner or pneumatic valve positioner. There are two kinds of valve structures: one is to install the reinforced PTFE soft seal seat and the other is 1Cr18Ni9 or 0cr18ni12mo2 (TI) hardfacing all metal hard sealing seat made of stellite alloy. It is used in normal temperature and high temperature (- 40 ℃) respectively. The product features high transmission efficiency, large thrust, good sealing performance, large rated flow coefficient and strong interchangeability of parts. Due to the shear effect when the valve core and valve seat are closed, it can be especially used for the medium containing fibrous filaments, particles or extremely high viscosity. Therefore, it is widely used in paper-making, petroleum, chemical, pharmaceutical, metallurgy, textile, sewage treatment and other production departments in the medium flow, pressure, liquid level, temperature regulation, in order to achieve automatic control process, the production process according to certain specifications.

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Also turn a few times to see if it is skewed, because during transportation, it is easy to bump the stem. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
