Qingdao Hexin Machinery Co., Ltd. produces various valves for petrochemical engineering, cast plate flue butterfly valves, large flue baffles, sealed double baffles, wide-screen flue baffles, pneumatic flue butterfly valves
valve plate
The spherical ink has good performance and can be formed at one time, with excellent corrosion resistance, thermal deformation resistance, advanced combination, good sealing performance, no stuck, ensuring long-term reliable operation, the product is widely used in China
Casting valve plate flue butterfly valve
Casting butterfly valve is a special fire-resistant butterfly valve. The valve plate is integrally formed, and the material is generally a three-dimensional structure of ductile plate or stainless steel, which is resistant to deformation, butterfly valve and corrosion resistance.
Large flue baffle
With the expansion of the scale of petrochemical plants, the specifications of flue baffles are also getting larger and larger. Our company actively improves and perfects the design and manufacture of large-scale flue baffles, and has many application achievements. Boards have significant advantages.
Sealed double baffle
The sealing air double baffle is a kind of baffle or butterfly valve that can achieve 100% isolation. Its structural characteristics are mainly that the valve plate is a double-layer structure, and the cavity in the middle of the double-layer valve plate is passed into the sealing air, and the pressure of the sealing air is higher than that of the pipeline. Internal medium pressure to achieve full sealing.
Pneumatic rectangular flue baffle
The flue baffle is a valve installed on the flue air duct of the heating furnace for switching or adjusting functions. The flue baffle is complete with an actuator, usually a pneumatic or electric actuator.
Pneumatic flue butterfly valve
Design and manufacture of various specifications of pneumatic flue butterfly valve. Using ASCO series solenoid valve, FISHER, Siemens and other intelligent positioners, external maintenance-free self-aligning wear-resistant rolling bearings, structural design, reliable operation.
