Product Name: Mud Val
Product Model No.：SD44X-10
SD44X Manual fast open mud valve
1. Product characteristics and applications
The product is mainly installed on the outside of all kinds of pools using for eliminating mud and sewerage at the bottom of pool.
2. Working principle
The valve mainly consists of valve body, valve flap, valve cap, gear case, gear rack handle, threshold and so on. During operation, only if press handle down to position may the valve start. On the opposite direction, may stop fast.
3. Main technology parameters
Test pressure PN(Mpa)
Applicable temperature ℃
Water, sewerage, mud
4. Main part material
Material of valve body, valve cap and gear
Valve flap material
5. Maintenance and installation points for attention
1. The valve must be kept in drying and ventilation room. Prohibit stacking. In order to prevent rubber from aging and to affect working lifetime, applicable temperature should be kept in the limit of 0-35℃,and relative humidity should be remained in the range of 50-80%.
2. Should avoid contacting liquid fuel, oil and other flammable materials.
3. For the valves in stock, two ends of the path must be sealed in order to avoid foreign matter entering interloculum so as to impair related sealing element.
4. Before install the valve, should check carefully if the operating condition of the pipeline conforms to the regulated applicable scope of the valve. Prevent unnecessary impairment from happening because of improper selection.
5. During operating, must not rely on lengthening lever in order to avoid impairing driven parts such sealing surface, gear case and so on because of excessive torque.
6. During intallation, should clean interloculum of the valve avoidng dirt clogging or impairing sealing element. As well should check periodically according to practical condition.
7. During operating, must check the sealing position contacting media as well as other easily-worn parts frequently and check periodically according to actual usage.
8. If the valve is used for discontinuous operation pipelines, clean the position contacting media when stops running in order to prolong working lifetime of the valve.
9. For the repaired valves, should do sealing property test with no exception. After the test is past, install, use, as well make a report for reference.
6. Fault and elimination methods
1. Valve stem on-off not flexible
Clogging between gear case and valve stem
Process the burr problem on valve stem.
Existing foreign matter between gear case and valve stem
Eliminate foreign matter.
2. Leakage between sealing surfaces
Gear handle not closing to expected position
Adjust the shift to close geae handle to expected position.
Sealing surface of valve flap impairing
Replace valve flap.
Sealing surface of valve body impairing
Replace valve body.
7. Main profile dimension and connection dimension
