HZVI Valves Overrides

XLHJ Series

Main application

- The declutchable worm gear is coordinated with the pneumatic device, used for manual and pneumatic driving of the 90°span butterfly valves, ball valves and plug valves.

Features

- It’s small and light, with reasonable design and creative design; - The series of pneumatic output torque devices are coordinated with

various valves; - There are two key grooves 90° away at the inner connecting hole of

the worm wheel, which can facilitate the user to select the relative position of the device on the valve body;

- Raise the spacer pin and rotate the eccentric device for 180°, the spacer pin will automatically stop the device to achieve pneumatic transmission; conversely, it will achieve manual transmission;

- When delivered out of the factory, it’s filled with special lubricating grease. After coupled with the valve, it’s integral sealed, dust-proof and water-proof, with the protection rating of IP65.

XLHJ Series

Instructions for Use

The bottom of the reducer is connected with the valve, with the bracket surface connected with the cylinder, shaft coordinated with the inner hole of the worm wheel and the terminal square of the shaft coordinated with the square hole of the cylinder (working process: in the pneumatic state, the cylinder drives the shaft and the worm wheel rotating with it simultaneously; in the manual state, the worm wheel is geared with another one and drives the shaft and cylinder piston rotating with it simultaneously.) When rotating the handle (outward by 180°) for folding the worm stem, it may be jammed; at this time, you need to rotate the handle for an angle. The pneumatic and manual transmission can’t be activated at the same time.

Main application

- Used for manual and pneumatic driving of the 90°span butterfly valves,

ball valves and plug valves.

Structure features

- It’s small and light, with reasonable design and the big output torque;

- With limit screw can be fully open or fully close to adjust at the two

positions

- Worm gear can be in any position to achieve self-locking,, easy to operate

- Switch Indicator directly connect on the worm gear, the indicator is direct

and accurate

- There are two key grooves 90° away at the inner connecting hole of the

worm wheel, which can facilitate the user to select the relative position of the device on the valve body

- When delivered out of the factory, it’s filled with special lubricating grease.

After coupled with the valve, it’s integral sealed and water-proof, with the protection rating of IP65

Install procedure

- Firstly check whether the worm gear inner bore, key groove, housing flange of the device and the stem axis, key, valve mounting flanges are consistent with;

- After Checking correctly, the device will be installed in the valve; - Turn the hand wheel on the device, adjust the limit screws so that the indicator on the

indicator plate can be fully closed when the needle points to close, fully open when the point open.

Maintenance

- Shall not exceed the rated operating conditions of the device used under conditions - Lubrication conditions regularly checked every two years
