Detailed Product Description：	Bypass valve F963H-4 Nominal diameter: DN300 × 2 / 400 Major parts material: Name of Material Carbon steel body Cr-Mo steel valve Nitriding steel stem Steel bonnet F963H-4 performance parameters: DN (Mm) Electric Actuator Model output torque () The output angle (Degrees) angle valve switch (Degrees) 300 × 2 (Right) DKJ-400 600 0 ~ 90 0 ~ 70 300 × 2 (left) DKJ-400 600 0 ~ 90 0 ~ 70 Bypass valve Model No. Nominal Number List Path DN (mm) Nominal Pressure PN (MPa) maximum media Flow (T / H) connection size OD × wall thickness (Mm) body Quality of materials (Kg) Remarks 1 P963H-4 22.2427.003 300 × 2 / 400 4 145 Φ325 × 25 steel steam bypass valve 1545 (right) Φ426 × 16 2 P963H-4 22.2427.004 300 × 2 / 400 4 145 Φ325 × 25 steel steam bypass valve 1545 (left) Φ426 × 16 First, use: 200MW units for high pressure boiler, installed in the cold reheater section of export pipelines, according to the requirements of reheat steam temperature, by changing the position of the disc, and modifications to the steam - steam heater and cut the flow of bypass pipe area, thereby regulating reheater steam temperature. Second, the structural description: 1. The valve is divided into left and right are two types of inlet and outlet are welded connection. 2. Left and right type addition to the different disc and instruction sheet, the other parts are interchangeable. 3. Valve with square shape, with a large open area, resistance characteristics. 4. Stem nitrogen treatment by the anti-corrosion, good resistance to corrosion and abrasion resistance properties. 5. Valve upper part of one-way thrust ball bearings embedded, open and close freely. 6. DKJ-400 valve with electric actuator, the output shaft torque and output shaft angular displacement 0 ~ 90 ° angle, the valve switching angle is 70 °, automatic control valves. Third, the installation instructions: 1. Valve must be installed vertically, the valve stem up. 2. As the two export branch are Φ325 × 25mm, therefore, assembled on the ground, should be carried out strictly in accordance with plans, make the necessary flow of tags. 3. Tongue-shaped part of the valve position on the gas - gas heater side of the centerline of the right side through the valve, 8 °, lever on the dashboard lights should be aligned with the direction of the zero off. 4. Electric actuator body and lever connected to a "just" sexual connection, connecting rod should not exceed a maximum 2m. Link should not appear "S" shape or other curved case, and instructions are not allowed to randomly change the direction of needle valve off under zero or arbitrarily change the dashboard position.
