Pneumatic eccentric half pneumatic valve operating instructions _ pneumatic components factory valve industry

Pneumatic valve pneumatic pneumatic valve pneumatic eccentric half overview: pneumatic components factory eccentric valve industry production of pneumatic half pneumatic valve is a blend of the traditional v-shaped with respective advantages of eccentric rotating valve, pneumatic valve is designed to meet the special working condition of self-developed high-tech products. Pneumatic eccentric half pneumatic valve technology parameters: pressure rating: PN1. 6 ~ 10. 0 mpa diameter range: DN25 ~ 600 mm applicable temperature: - 196 ℃ ~ 560 ℃ pneumatic eccentric half pneumatic valve features: (1) pneumatic eccentric half pneumatic valve on the basis of the traditional v-shaped pneumatic valve increases the distance of eccentric rotating valve, closing a pneumatic core eccentric force, make the pneumatic clamping ring, so as to achieve zui better sealing effect, standard configuration for zero leakage, namely open air core in the opening moments and sealing ring out quickly, in any intermediate position and no friction sealing ring, eliminate the sealing surface wear, greatly improving the service life, keep the v-shaped adjustment of traditional V pneumatic valve, flow control is relatively accurate, which integrated the advantages of the two valves, both the resistance to erosion of eccentric rotating valve, strict sealing and v-shaped adjustment precision of the pneumatic valve. (2) all products are metal sealing zero leakage and sealing surface using department too, hard alloy welding or tungsten carbide spray after especially suitable for very harsh working conditions, such as coal chemical blackwater regulation, ash chemical containing powder medium, such as all kinds of grey powder input containing particles. (3) flow characteristic is approximate equal percentage and quick opening two, can be respectively used to adjust and to cut off the occasion. (4) using the special eccentric structure, with upper and lower oilless bearing, valve stem and pneumatic core using spline connection, thus greatly improving the reliability of valve action. (5) the pneumatic core shearing action with the sealing ring in the process of the switch, fiber and extrusion particles, can cut off the medium is especially suitable for pulp or powder fluid with fiber particles. 6 can choose v-type PTFE and flexible graphite packing, used for a variety of different conditions, and can be equipped with vacuum sealing, etc according to the requirement of special seal, with a new generation of double piston gear rack type pneumatic actuators, has compact structure, big output power, long life and other advantages, have both regulation and to cut off the two functions, are interchangeable with electric actuators, widely used in chemical industry, electric power, textile, food, medicine, paper making industries to cut-off or adjust the control of process medium, especially suitable for such as blackwater regulation of coal chemical industry, the ash chemical powder containing medium, such as all kinds of grey powder conveying occasions, including particle is the replacement of the traditional eccentric rotary valve pneumatic eccentric half pneumatic valve selection methods: customers when choosing pneumatic eccentric half pneumatic valve, must confirm which product model (2) nominal size (3) nominal pressure (4) body material (5) trim material 6 connection mode need 7) using temperature actuator type switch or external regulation pet-name ruby whether need attachment whether attending the match solenoid valve explosion. : PQ640F/H/Y pneumatic eccentric eccentric PQ940H electric pneumatic valve and valve pneumatic hard seal characteristics of pneumatic valve
