PRESSURE TESTING FACILITIES

BEL Valves have a comprehensive range of product testing facilities. Results are captured using computer based Data Logging. Test facilities include safety cells for high pressure or high risk testing, with remote visual monitoring via closed circuit TV.



Range of test facilities include:-
• Cryogenic / Low temperature down to – 196 degrees Centigrade
• High Temperature – up to 300 Degrees Centigrade
• Gas testing (typically Nitrogen)
• Leak Detection using Nitrogen / Helium gas mix and Mass Spectrometer
• High Pressure Testing:
- Hydrostatic – up to 10000 Bar (150000 psi)
- Gas – up to 1550 Bar (22500 psi)

VALVE OVERHAUL AND RE-CERTIFICATION

BEL Valves offer a full Service backup for equipment overhaul and re-certification on all work undertaken, all work is guaranteed.



All work is carried out by Qualified BEL service technicians, Dismantling / Inspection Reports (supplemented by photographs of equipment) are completed and sent to the Client with a quotation.
FAT where possible (Client approval) the original test specifications will be carried out on the repaired equipment for re-certification purposes.
Equipment being overhauled at BEL can be upgraded to the latest designs in seal technology and hard coating choices giving a longer working life expectancy than the original design.

Example of Options available:-

1. Lip seals replacing O Rings on the Seat Rings
2. Tungsten Carbide replacing Stellite 6 as supplied on older models.

VALVE MODIFICATION

When requested by clients, BEL Service will investigate the possibility of modifying existing valves in the process lines or which they have currently hold as spares.

This gives the client greater potential in utilising stock which they may consider as redundant.

The costs for modification against buying of new equipment is greatly reduced allowing major savings for the client.

Modifications carried out to date:-

- Manual Operated Valves to Electric Actuators
- Manual Operated Valves to either Hydraulic or Pneumatically operated linear actuators with controls
- Hydraulic and Pneumatic actuators to increase the speed of operation for use in ESD systems.
- Slab Gate valves to Split Gate Valves for double block and bleed capability.
- Changing of valve body end connections to allow greater use of stock valves.

REFURBISHMENT OF GATES, SEAT RINGS AND STEMS

It is BEL Valves policy of reducing the costs to the end users, when possible the original Gates, Seat Rings and Stems are repaired by replacing the Tungsten Carbide coating on the Gate and Seat Ring sealing surfaces and applying a coating of the super finish diameter (packing area) of the Stem.

In most cases the repair costs are a minimum of 60% less than the cost of new parts.

DESIGN AND MANUFACTURE OF TOOLING

BEL design tooling on request to allow in line maintenance on all of our products, these cover the following:

• Actuator removal on valves in the horizontal plane (sizes 16” and Above)
• Gate Removal
• Removal and installation of Seat Rings in the valve body chamber
• DE-Springing of Actuators

Seat Extraction Tooling details



Hydraulic Actuator dismantling / Assembly Tooling

De-Springing Tooling



Hydraulic Spring Return models only

Used on the removal and re-assembly of the spring located inside the actuator. This design of tooling has been used extensively in BEL in assembly and on numerous site visits when servicing equipment supplied by BEL. Safety measures are incorporated in the design to ensure safe working practices and methods are used.

Seal Sizing Tools

This equipment is supplied and used in two parts; First stage Seal assembly and Second stage Seal assembly. This is to ensure the sealing edges and designed dimensions of the seals when fitted are achieved.



First Stage Seal Assembly

Equipment is used on all piston seals when being fitted. These ensure the seal is fitted without over stretching causing damage when being fitted into the closed groove located in the piston diameter.

Second Stage Seal Assembly

Equipment is used on all piston seals when being fitted. These ensure when the seal is fitted into the closed groove located in the piston diameter, the sizing rings are pulled over the seal and left to assist the seal to return to its original size.

HYDRAULIC CONTROLS AND HYDRAULIC ACTUATORS

BEL also give service backup of our hydraulic /pneumatic controls and hydraulically operated products using our trained service technicians. These cover the following:-

• Routine Maintenance / Repair
• Fault finding
• Flushing of the controls / Actuators using any of the following methods:-
• Standard Flushing (Mineral or water based fluids)
• Hot oil Flushing
• Chemical Flushing

All cleanliness fluid levels to a minimum of Nas 6 or ISO fluid / system cleanliness are checked and verified using the following equipment:-



Contamikit used for measuring the contamination level of the hydraulic fluid.

Hydraulic Fluid samples are taken and placed on a membrane filter and ensures its molecular distribution under a microscope in the same manner as such standards as JIS B 9930 and SAE ARP 598 A. The results are compared with standard contamination disc. The instruments are portable and are used on site.

CUSTOMER PERSONNEL TRAINING

This can be carried out at BEL Newcastle, England or on site (available upon request). The training will include the following as a minimum requirement:-

- Design technology (the design make up of the equipment)
- Methods of functioning the equipment
- Hands on (examine parts and build/dismantle the equipment)
- Fault Finding
- Routine Maintenance methods and procedures to be used

Duration is dependant on the detail standard required by the customer.
