An introduction to TMK Valve Group Truemark
International, the parent company of TMK Valve
Group has been supplying US manufacturers with
castings and finished Valves from Asian factories
for over 20 years. During this time, it has
forged strong relationships with the owners of
the very best Asian Valve manufacturers.TMK
Valve Group is a joint venture between Truemark
and these manufacturers to establish a trusted
supply route into the US, Europe and the Middle
Eastern markets, levering on the relationships
made by Truemark and its principals throughout
the world. TMK products are focused firmly on
the Oil Gas sector and all products offered
carry the relevant API and CE markings.TMK
Valve Group carries stock at it's Stafford Texas
headquarters and can deliver non-stock items and

Ball Valves

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.

Ball Valve Specifications

• Sizes
• 1 thru 48 full or reduced port
• Pressure Class
• ANSI B16.34, API 6D and ANSI 150 -2500.
• Bi-directional Sealing
• TMK-OVK Ball Valve is a true bi-directional
  valve. Being fully symmetrical, it will
  effectively seal pressure from either direction
  without the risk of pressure lock. Trunnion Ball
  Valves are Double Block and Bleed.
• Fire Safe
• API 607 and 6FA
• Body to Bonnet Seal and Body to Body Seal
• A metal-to-metal seal is achieved between the
  body and bonnet using TMK-OVK metal-to-metal
  sealing technology. Other arrangements to
  achieve connective position of the body and
  bonnet or body is double sealed by gasket and
  o-ring
• Temperature
• -320 Degree F (Cryogenic) to 1500 Degree F.

• End Connections
• RF / RTJ / Welded End / Hub End
• Leakage Class
• Bubble tight for soft seated Valves
• Class v and VI for metal seated
• Stem Extension
• For the buried service, the stem can be
  lengthened. For the convenience of operation, the
  corresponding compound injection nozzle,
  drainage valve and release valve can be extended
  to the top of the valve.
• Available Materials
• Cast Steel

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.

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.?
