Pneumatic Valve Hand wheel
A pneumatic valve hand wheel is an essential component in many industrial and mechanical processes. It’s a manual device that allows operators to control the operation of a pneumatic valve by physically turning the wheel, providing an alternative or backup means of actuation when automated systems are unavailable or not functioning correctly.
The handwheel works through a simple mechanism. As the wheel is turned, it operates the valve stem, which in turn opens or closes the valve, thereby controlling the flow of the medium—be it gas, liquid, or steam—through the system. The direction and degree to which the handwheel is turned determine the extent of the valve’s opening or closing.
Pneumatic valve hand wheel are often used in situations where precise control over the valve operation is necessary, or where it’s important to have a manual override for safety or operational reasons. They are typically found in various industries, including oil and gas, water treatment, and manufacturing, among others.
One of the key advantages of pneumatic valve handwheels is their simplicity and reliability. Because they’re manually operated, they’re immune to electrical or electronic failures and can be used even in harsh or challenging conditions. This makes them a vital part of many safety and emergency systems.
Moreover, modern pneumatic valve hand wheel often come with features that enhance their usability and functionality. For example, some models have locking devices to prevent unauthorized or accidental operation, while others may include indicators to show the valve’s position at a glance.
In conclusion, the pneumatic valve hand wheel is a simple yet highly effective device for controlling the operation of pneumatic valves. By providing a reliable and straightforward means of manual actuation, these handwheels contribute significantly to the safety, efficiency, and versatility of various industrial and mechanical systems.
Pneumatic actuator hand wheel operating box main purpose:
The handwheel mechanism is used in combination with a pneumatic device for opening a 90° butterfly valve, ball valve, etc., for manual or pneumatic driving.
Pneumatic hand wheel operating box features
※ Product serialization, the output torque is matched with pneumatic devices and valves.
※ Small in size, light in weight, reasonable in design and novel in style;
※ Pneumatic and manual. Rotate the eccentric 180° and the handle is in the manual (ON) position for manual operation. The handle is located in the pneumatic (OFF) position and is pneumatically operated.
※ The worm wheel connection inner hole is made of two key grooves separated by 90°, so that the user can select the position of the device opposite to the valve body as needed.
※ The product is equipped with special grease. After assembly with the valve, it is sealed, dustproof and waterproof. The protection grade is IP65.
