Ball Valve
Relia is a China ball valve manufacturer and supplier, supplying quality ball valves, including trunnion mounted ball valve, floating ball valve, metal seated ball valve, fully welded ball valve and top entry ball valve; Class 150, 300, 600, 900, 1500, & 2500. The size covers: 1/2" -60" (DN15-1500), with flanged, welding or threaded ends.
A ball valve is a type of valve that uses a spherical perforated obstruction (a rotary ball) to stop and start the hydraulic flow. A ball valve is usually rotated 90° around its axis to open and close. It is one of the most widely used valve types. Ball Valves are suitable for both liquid and gas services.

How Is a Ball Valve Tested?
Hydrostatic Shell Test
-Hydrostatic Shell Test Preparation, Method and Acceptance Criteria
Ball Valve ends shall be blocked and the closure member placed in the partially open position during the test. When present, relief valves that release to the atmosphere shall be removed and their connection points
plugged. Internal non-return valve shall be installed on sealant injection ports without the injection fitting.
The test pressure for the hydrostatic shell test shall be a minimum of 1.5 times the pressure rating conforming to
4.3 for material at 100 °F (38 °C) based on the valve end connector material. The test duration shall conform to
Table 9 based on the valve end connector size.
- Extended Hydrostatic Shell Test
When the valve has been designed to withstand a higher hydrostatic shell test pressure per 5.5, the shell test
pressure shall not be at less than 1.5 times the higher design pressure at 100 °F (38 °C).
When performing a higher hydrostatic shell test and the valve is flanged, the hydrostatic shell test shall be
performed with bore sealing plugs that ensure the flanges are not subjected to test pressures greater than 1 .5
times the valve flange rating.
The test duration specified in Table 9 shall start after stabilization.
There shall be no visible leakage permitted during the hydrostatic shell test.
Minimum Duration of Hydraulic Shell Test
| Valve Size | Test Duration(minutes) | |
| NPS | DN | |
| ≤4 | ≤100 | 2 |
| 6 to 10 | 150 to 250 | 5 |
| 12 to 18 | 300 to 450 | 15 |
| 20 and larger | 500 and larger | 30 |
| FOOTNOTE= Test duration starts once the valve is stabilzed per manufacturer's procedures. | ||
Seat Test
Hydrostatic Seat Test Preparation, Method and Acceptance Criteria
Lubricants or sealants shall be removed from seats and closure member sealing surfaces except where the
lubricant or sealant is the primary means of sealing.
NOTE See K.1 4 for guidance on performing alternative hydrostatic seat testing.
The test pressure for all seat tests shall be a minimum of 1 .1 times the pressure rating conforming to 4.3 for
material at 100 °F (38 °C) based on the valve end connector material. The test duration shall conform to Table
10 based on the valve end connector size.
Minimum Duration of Hydraulic Seat Test
| Valve End Connector Size | Test Duration (minutes) | |
| NPS | DN | |
| ≤4 | ≤100 | 2 |
| 6 to 18 | 150 to 450 | 5 |
| 20 and larger | 500 and larger | 10 |
| FOOTNOTEa Test duration starts once the valve is stabilized per manufacturer's procedures. | ||
Seat leakage shall be monitored from the downstream side of the seat when under hydrostatic seat test.
The acceptance criteria for leakage shall be as follows:
― For soft-seated valves and lubricated plug valves: leakage shall not exceed ISO 5208, Rate A (no visible
leakage for the duration of the test at test pressure).
― For metal-seated valves, other than check valves: leakage shall not exceed ISO 5208, Rate CD.
NOTE The test procedures for various types of block valve are specified in 1 0.4.3.
― For metal-seated check valves: leakage shall not exceed ISO 5208, Rate E.
On completion of hydrostatic seat testing, parts such as drain plugs and cavity-relief valves, shall be fitted in
conformance with the manufacturer’s documented procedures.
Ball Valves Applications
The Ball Valve are mainly for Oil & Gas production, Refineries, Chemical and Petrochemical Complexes, Power Industry for on off function.
Gas and Oil production: In subsea isolation and shut-down facilities, For oil-head isolation, pipeline surge control, processing separation, storage, transmission and distribution, secondary and enhances oil recovery.
Refineries: As shut-off and isolation valves for tower bottom lines and thermal-cracking units; Gas/Oil separation lines, Gas distribution measuring, metering and pressure regulation stations, Oil loading control stations, Pumping and compressor stations, Emergency shut-down loops, Refining units, etc.
Chemical and Petrochemical Complexes: For low differential pressure control, For emission control, For handling highly viscous fluids, abrasive slurries in process and storing facilities.
Power Industry: For boiler feedwater control, as burner trip valves, for control and shut-off for steam, etc.
Pulp and Paper industry: as shut-off valves, In pulp mill digesters, batch-digester blow service, liquor fill and circulation, lime mud flow control, dilution water control, etc.
