SEAT
Independent seats with preloaded springs are always in contact with the Ball a protect seal even at low pressure. The replaceable Seat rings and soft inserts can be supplied in materials to suit most service conditions. For very high Temperatures, sealing is ensured by metal to metal seats. Whereby the Ball and Seats are coated with Tungsten carbide and lapped together. Most Sizes and classes have sealant injection system fitted as standard. This allows emergency sealing to be carried out in the event of damage to the soft seat. |

STEM |
|
|
Stem are manufactured separately from the ball and feature an anti blow –out design. Stems are supported by RPTFE lined bushes, which reduce valve torque. Stem Sealing is by O-rings and graphite rings. And Graphite rings. From 2” and above stems are supplied with sealant injection system.

|
| BALL | |
| Balls are supplied in Forged or cast Stainless Steel, Duplex or Carbon Steel with ENP. The Trunnion Mounted design reduces operating torque and seat wear. | |
| ANTI STATIC DEVICE | |
|
Electrical conductivity is achieved by fitting a positive contact device between the Stem, Ball and Bonnet. |
|
| DOUBLE BLOCK AND BLEED | |
| Valves are equipped with a went plug, which allows the cavity to be relieved when pressure is applied to both sides of the Ball simultaneously. | |
| TESTS | |
|
Valves are tested in accordance with BS EN 12266 Pt 1&2, API6D, API 598 and ASME b 16.34.
|
|
| PACKING GLAND | |
|
The packing gland design is a two-piece self-aligning type. The gland proper has a spherical head that rides within the spherical joint of the gland flange. The gland proper has a shoulder, which restricts the complete entry into the stuffing box bore. This particular design assures a straight compression of the packing as the gland eyebolts are being equally adjusted, without injuring the stem.
|
|
| FIRE TEST CERTIFICATION | |
|
Valves are designed and certified by an independent authority according to API 607 and API 6FA.

EXTERNAL COATING |
|
|
Carbon Steel Valves are normally supplied with FAC standard paint finish. Valves can also be unpainted or finished to customers paint specification. ACCESSORIES Include locking devices, pipe pups, extended bonnets and actuators. Suitable materials, components, seats and O rings can be supplied for valves with Explosive Decompression Or Cryogenic applications |
