Supply - Three eccentric pneumatic butterfly - steel, 304

Three eccentric pneumatic valve Product Overview: Brand ZXDA Model D673H Material Cast iron, steel, stainless steel connection form folder structure on the wafer Medium liquids, gases, environmental pressure 1.0 ~ 2.5Mpa Operating temperature ≤350 ℃ Standard GB Flow direction Two-way Drive pneumatic parts and accessories actuator uses metallurgy, electric power, petrochemical type (channel position) two formula Product Overview: the use of sophisticated J-shaped elastic ring and three eccentric multi-level metal seal structure, is widely used in medium temperature last metallurgy, electric power, petrochemical, as well as drainage and municipal construction and other industrial pipe ≤425 ℃, and for regulating the flow and the carrier off fluid use. The valve adopts three eccentric structure, seat and disc sealing surface are made of different hardness and stainless steel production, with good corrosion resistance, long life, this valve has bi-directional sealing function, product line with the state GB / T13927-92 valve Pressure test standards. Features: This valve adopts three eccentric sealing structure, seat and disc almost no wear, the concept of having more tight sealing function. Ring made of stainless steel production, with a metal seal and elastomeric seal the dual advantages, both in the case of low and high temperatures, both with excellent sealing performance, corrosion resistance, long life and other characteristics. Disc plate sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life. Large size disc use a lattice structure, high strength, flow area, flow resistance. The valve has bi-directional sealing function, the installation of unrestricted flow of medium, is not affected by spatial location can be installed in any direction. Drive can multi-position (90 ° rotation or 180 °) to install, easy to use. Attachment Options: Depending on the requirements of the control and choice of the following accessories: back to the hearing: Also called limit switches, remote switch signal feedback (optional explosion proof). Solenoid valve: double acting election two five-pass, two-way single-action option (optional explosion proof). FRL: You can air regulator, filter, cylinder lubricating. Hand wheel: turn the hand wheel mechanism can be achieved manually open and close the valve. Electrical locator: 4 ~ 20mA input signal, valve adjustment. Order: This product is factory direct supply products, for (can be customized), when ordering the special configuration of the following detailed description parameters: (example: valve type, drive, connection type, structure type, nominal pressure, nominal diameter The input signal, sealing surface material, body material, suitable temperature, whether with attachments) Contact Inquiry ----> OK price ----> Fax contract ----> contract ----> Pay deposit ----> deliverables ----> settle payment
