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 can be used in normal temperature (- 40 ~ 200 ℃) and high temperature (- 60 ~ 450 ℃). 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 the process of liquid, chemical industry, chemical industry and so on.

 Please provide the following information when ordering
Product name and model;
2. Nominal diameter, nominal pressure, medium name and medium working temperature;
3. Valve action mode: air opening or air closing;
4. Type of actuator: double acting or single acting (spring return), domestic or imported, with handwheel;
5. Material requirements of valve body and valve internals;
6. Other supporting accessories;

1. Installation construction must be careful, 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. Turn it a few times to see if it is skewed, because Zui is prone to bump the stem during transportation. 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.
