The Introduction of Products
SQDY421F Manual hydraulic emergency shut-off valve
SQDY421F Manual hydraulic emergency shut-off valve is a necessary valve accessory in piping system. It is mainly used to quickly close the inlet and outlet of the pipeline at a distant location in case of emergency. Can implement remote control opening and closing, only need to press the control button to enable the other matters in the specified time to complete, such as installing remote signal feedback system, can be in the remote control room directly learn the valve running state.
The performance specification
Action principle and structure description
1. When the valve is in use, first turn the hand wheel counterclockwise to the end, and then use a fixed hand wheel to fix the nut, in case the manual device pulls the piston so that the seal is not in place and the seal is not sealed (the valve has been adjusted before leaving the factory). Under the condition of no external pressure operation, the valve disc is normally closed. When used in the system, the hydraulic source of the hand oil pump pushes the piston to move up to open the valve. When the valve needs to be closed or there is an emergency, the hydraulic source pressure can be discharged and the valve will automatically close.
2. The valve is equipped with operating handwheel to open or close the valve when there is no air source.
3. When the disc is closed, the pressure is achieved by relying on the hydraulic source of the hand pump or the operating handwheel.
4. The flow direction of valve working medium should be high into low out, and the flow direction of ordinary stop valve is just the opposite.
5. The connecting dimensions of valve flanges shall be in accordance with JB/T79.1-94 "Convex Integral cast steel flanges" or HG20592-97.
Main external dimensions and connection dimensions
Precautions for storage, installation and use
1. Both ends of the valve path must be covered with protective cover, stored in a dry, ventilated room, such as long-term storage should be regularly checked to prevent corrosion;
2. Do not remove the dust cover before installation of the valve, so that there is no dirt in the valve;
3. The valve can be installed in horizontal or vertical pipe for use, remove the dust cover when installing, and blow the pipe clean with air first, so as not to bring dirt into the valve cavity;

Application rules
Pneumatic cutting valve cylinder opening pressure ≥ 0.3-0.6mpa, the daily working pressure of the cylinder, shall not be less than 0.4mpa, to ensure the normal work of the valve.
Emergency cut-off valve should not be opened for a long time to avoid spring fatigue failure.
Installation Precautions
1. During storage, each external access of the valve is closed with plugs or cover plates and stored in a dry and ventilated room. Long-term storage should be regularly checked to eliminate dirt and coated with anti-rust oil on the processing surface to prevent corrosion.
2. Before installation, clean the valve and tighten the joint of each thread.
3. The cut-off valve adopts the principle of check valve, can only be one-way truncation, installation must pay attention to the valve mark, the end to be protected as the valve entrance. Valve installation should be noted: high in low out.
4. Flange sealing surface form, pressure grade and connection standard must be indicated when ordering.
Liquid Ammonia Emergency Cut-off Valve
QDY421f-16/40c liquid ammonia emergency cut-off valve combines the advantages of globe valve, check valve and pneumatic valve, using the lifting structure of globe valve and check valve to prevent the principle of media backflow. Shut-off valve has excellent technical performance, low load loss and high reliability, and remote hand pump matching use, using manual hydraulic control valve open - close.
The pipeline installation of multiple emergency shut-off valves should be controlled by two hand oil pumps, one of which is working and the other is standby to prevent the valve from working properly when one oil pump is damaged. In the case of multiple emergency shut-off valves, one (J23H-40P) needle valve is used for control. So that the service can be closed using a needle valve.
