Tianjin Beifang Valve Actuator Co., Ltd. 603 Series Instruction Manual
1
603 series valve gear box can provide a reliable position control of gate,
stop valves, as well as similar ones. They are used as the manual
operator attached with a handwheel. They also can be electric
controlled when combined with multi-turn electric actuators.
1. SUMMARIZE
1.1 Range of application
1.2 Brief For the adoption of the bevel gear pair, the compact profiles provide
603 series higher reliability and watertightness. All units fully O-ringed
sealed and permanently lubricated with molybdenum disulfide grease.
The thrust will be accepted by the thrust groupware, which provides
603 series high reliability.
The drive sleeve can be dismounted independently. It transmit torque
in the type of plug sleeve and bore with keyway. It also bear thrust in
the type of copper alloy stem nut.
603 series have varies input mechanism for combining with multi-turn
electric actuator.
Sizes 6032~6034 could be furnished with spur gear attachments to
reduce manual operating force.
2. TECHNICAL DATA

3. LUBRICATION
If the electric actuator combined with 603 series has self locking
characteristics, do not attempt to remove the unit from a valve on a
pressurized line. Removal of the gear box may cause imbalance of the system.
5. INSTALLATION AND
DISASSEMBLY
603 series utilize a totally sealed case. The driving members in
the main case are lubricated with 2# molybdenum disulfide
grease, and it is not need to refresh the grease periodically.
Please use the grease with the same trademark or the same
performance if replacement of grease is necessary.
4. STORAGE
1.1 Connection of plug sleeve 1. Place valve in closed position.
2. Mount the actuator on the valve mounting flange, locating
the valve shaft and the actuator drive sleeve correctly.
3. Turn actuator input shaft until the unit is in correct position.
4. Bolt the actuator securely to the mounting flange.
1.2 Connection of stem nut 1. The stem nut will be supplied with a pilot hole. The
consumer should take off it and cut thread.
3. Place valve in closed position.
4. Clockwise rotate the input shaft (the valve stem is left-hand
thread) and mount the actuator on the valve mounting flange.
5. Turn actuator input shaft until the unit is in correct position.
6. Bolt the actuator securely to the mounting flange.
a) Dismount the bolts.
b) Dismount thrust bearing race, thrust bearing and stem nut.
2. Mount the stem nut as follows:
a) Ensure that the thrust bearing and O-ring is clean.
b) Check and ensure that the mounting flange is clean.
c) Apply the incidental grease to O-rings mounted on the stem
nut and the thrust bearing race.
d) Re-insert thrust bearing, stem nut, thrust bearing and thrust
bearing race in turn.
e) Mount the bolts.
Actuators should be stored in a clean, dry, protected warehouse.
Actuators should be stored on wooden skids to protect the
machined mounting flange, and input shafts should be coated
with rust proof oil to prevent from corrosion.
Input shafts should be rotated every two or three months to mix
the lubricant.
WARNING！
If the gear box is mounted on valve, attach ropes or hooks for the purpose of
lifting by hoist to valve and not to the gear box.
