Elektrikli eksantrik yarım küre vanaların profesyonel üreticisi
Our professional manufacturer of electric eccentric hemispheric valves specializes in six product lines based on their application: genel amaçlı vanalar, boru hattı vanaları, slurry valves, gaz vanaları, petrochemical valves, ve toz haline getirilmiş kömür enjeksiyon valfleri. We offer manual, pnömatik, and electric transmission methods, eight pressure levels (PN 0.25 ile 10.0 MPa), ve yüzlerce spesifikasyon (40 ile 00 for the largest eccentric hemispheric valve).
Professional manufacturer of electric eccentric hemispherical valves Application Areas
It is an upgraded product for gate valves, küre vanalar, Y-type valves and ball valves in the petroleum, kimyasal, metalurji, electric power and gas industries. It has been used in coal powder injection in the steel industry, bulamaç, mother liquor and alumina powder transportation in the alumina industry, hidrolik (veya kuru) enerji endüstrisinde kül giderme, petrokimya endüstrisi, gas industry and other occasions.
Professional manufacturer of electric eccentric hemispherical valves Applications:
Universal valves: Rationally designed and compact, they offer low flow resistance, excellent sealing, and easy and flexible operation. They are particularly well-suited for low-pressure pipelines handling media such as water, kanalizasyon, buhar, and paper pulp. They can be equipped with electric or pneumatic actuators, enabling remote automated operation. (For non-corrosive media such as water, buhar, kanalizasyon, paper pulp, and mud)
Professional manufacturer of electric eccentric hemispherical valves Advantages:
1. The side-mounted design is compact and lightweight, making it suitable for applications requiring limited installation space.
2. Düşük sıvı direnci, with a resistance coefficient equivalent to that of a pipe section of the same length.
3. Basit yapı, compact size, ve hafif.
4. A cutting function that can cut debris (such as branches and textile bags) from the medium when closing.
5. Sıkı ve güvenilir: The sealing surface of ball valves is widely made of plastic, which provides excellent sealing properties and is widely used in vacuum systems.
6. Easy operation and quick opening and closing: A simple 90° rotation from fully open to fully closed facilitates remote control.
7. Kolay bakım: The ball valve has a simple structure and the sealing ring is generally removable, making it easy to disassemble and replace.
8. Tamamen açık veya tamamen kapalıyken, the sealing surface between the ball and the valve seat is isolated from the medium, preventing erosion of the valve sealing surface when the medium passes through.
9. Geniş bir uygulama yelpazesine sahiptir, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball is rotated 90 derece, the inlet and outlet should be completely spherical, thus cutting off the flow.

Please follow the following instructions for installation when purchasing our products:
A: Remove the protective caps on both flange ends and flush with the valve open. b: Kurulumdan önce, the entire valve must be tested using the specified signal (electric or pneumatic) to prevent vibration from transport that may affect performance. Installation is permitted only after passing the test (wiring must follow the electric actuator wiring diagram).
C: Before connecting to the pipeline, flush and remove any remaining impurities from the pipeline (these impurities may damage the valve seat and ball).
d: During installation, do not use the valve actuator as a lifting point to avoid damage to the actuator and accessories.
e: This valve should be installed in a horizontal or vertical position on the pipeline.
f: The pipeline near the installation point must not sag or be subject to external forces. Use pipe supports or other supports to eliminate pipeline deviation.
g: After connecting to the pipeline, cross-tighten the flange bolts to the specified torque.
When the application is very important or the environment is complex, please provide design drawings and detailed parameters as much as possible, and our technical engineers will review and check them for you.
