6. Ball Valves

7. Special Service Valves
Forged or Cast Body & Bonnet
All types of Ball Valve bodies and bonnets are manufactured from forged or cast AISI 4130/4140 low alloy or stainless steel. Other materials for extreme service, such as Inconel or Duplex stainless steel are available to order.
Metal-to-Metal Seat to Body Interface
Precision lapped faces between the ball and seat ensure a metal-to-metal pressure tight seal . Seat is lapped on both surfaces to give a true metal to metal seal between the body, ball and seat. The stem seal is further reinforced and protected by a lip seal, giving bubble tight sealing.

8. Ball Valve Specifications

10. API 6A Gates
The TMK Gate Valve was developed to satisfy the need for a high quality reliable valve which is reasonably priced. All TMK Gate valve makes full use of modern materials and manufacturing techniques. It is easy to maintain, conforms to international design requirements and Quality Assurance Program. All TMK Gate Valve are manufactured to API 6A Specification as a basic minimum, in a Plant that is API Q1 and ISO9001 approved and Certified.
Forged or Cast Body & Bonnet
All types of gate valve bodies and bonnets are manufactured from forged or cast AISI 4130/4140 low alloy or AISI 410 SS steel. Other materials for extreme service, such as Inconel or Duplex stainless steel are available to order.

11. Sealing Metal-to-Metal Seat to Body Interface
Precision lapped faces between the gate and seat ensure a metal-to-metal pressure tight seal is maintained.
The Seat is lapped on both surfaces to give a true metal to metal seal between the body and seat.
This seal is further reinforced and protected by a Teflon or Viton lip seal, giving bubble tight
sealing performance at pressure below 10 psi.

12. Gate Valve Design Gate & Seat Design for Slab Gate
The seat in the gate valve are fully floating, this combined with a solid slab gate gives a true downstream seal resulting in exceptionally low operating forces.
Gate & Seat Design for Expanding Gate
The expanding gate creates a positive mechanical seal across the seats with or without line pressure. Floating seals with resilient seals allow the seats to be tightly wedged into the seats pockets in the open or closed position.
Bi-directional Sealing
All TMK Gate Valves are true bi-directional valve. Being fully symmetrical, it will effectively seal pressure from either direction without the risk of pressure lock. If the valve is used in uni-directional application, the gate and seats can be reversed to give a extra service life.
Gate Guided
The gate is guided positively by the valve body and close fitting stainless steel skirts. The skirts minimize the ingress of well fluid mud and sand into the body cavity.
Body to Bonnet Seal
A metal-to-metal seal is achieved between the body and bonnet using advanced metal-to-metal sealing technology. The seal ring is re-useable.
Non-rising Stem with Backseat
The stem used in the TMK gate valve is manufactured from Alloy-Nitride or 17-4 stainless steel. Being of the non-rising design, valve operation will not increase the pressure in the body cavity. Seal against the bonnet, providing means to replace the valve stem packing with the valve is under pressure
Stem Seal
All stem seals are non-elastomeric and are inert to most known liquids and gases. Being made from PTFE/R-PTFE stem frictional resistance is minimized resulting in lower operating torque. The stem seal design is suitable for all temperature range and services. Graphite stem packing is option.
Bearing
Heavy duty thrust bearing are used to absorb stem thrust and reduce operating torque. A grease fitting is located on the bearing cap to allow for lubrication to ensure continued trouble-free operation.。
