The clutch manual operating mechanism is a manual valve drive device typically used in conjunction with a pneumatic actuator. When the air supply signal fails, preventing the valve from opening, closing, or remaining in a fixed position, this manual operating mechanism offers a reliable solution. Operators can control the valve manually using the handwheel, ensuring the system's continued operation and safety.
The core components of the manual operating mechanism include the handwheel, transmission device, and connection components. The handwheel serves as the primary interface, allowing the user to precisely control the valve. The transmission device converts the rotation of the handwheel into valve movement, ensuring smooth and accurate operation. The connection components link the handwheel to the valve, enabling manual control.
The design of the manual operating mechanism takes into account the need for quick and reliable operation in case of pneumatic system failure. It not only plays a crucial role during air supply faults but also provides flexible control in certain special situations

Operation |
In normal operation, the handwheel is retracted and locked with a fastening nut, serving as a limit device for the valve's highest position. For manual operation, loosen the fastening nut, rotate the handwheel, and connect it to the actuator’s push rod, allowing movement of the push rod to adjust the valve opening. |
We can design and develop according to the needs of our customers to meet the requirements of different clients.

A globe valve fitted with an electric actuator is the right call when one line item has to close drop-tight on demand and still throttle flow within a few percent of setpoint. Ball and butterfly valves usually cost less and waste less pressure, but they give away control authority in the low-lift range where dosing, s...
READ MOREA process line that keeps drifting from its set point is rarely a controller problem. More often, the culprit is the flow control valve: wrong type, oversized trim, or an actuator that cannot respond fast enough. Flow control valves are the final element in nearly every control loop, and their performance decides whet...
READ MOREA water treatment plant in a coastal region was replacing carbon steel ball valves every twelve months. Chlorinated water was pitting the bodies and corroding the seats. The engineering team switched to 316 stainless steel ball valves, and the same valves passed three consecutive annual inspections without repair. Tha...
