These  special  line  of  valves  have  all  the  design  features  of  standard resilient  seated  valves  plus  the  specific  advantage  of    TEFLON  for  use in   CORROSIVE  ENVIRONMENTS  (Ideal  for  CHEMICAL  INDUSTRIES).It  also  solves  the  common  contamination  problem  available with Control & On- Off option.


 

The salient features of TDK Teflon lined valve are:

• PTFE sleeve backed with elastomer provides tight shut off
•PFA/FEP encapsulated disc with high strength metal insert
• specially designed gland sealing arrest leakage through spindle
• disc also available in high alloy material and PVDF/PFA coating for specific application.

 

 

Disc also availble in higher alloy material like ALLOY-20, 904L ,R- 55,HAESTALLOYC for specific application mounted with desired actuator i.e Manual Hand lever, Gear Operated, Pneumatic Cylinder Operated , Pneumatic Rotary Actuator,& Electrical Actuator.

Sizes: 50 mm to 600 mm

TDK RUBBER LINED BUTTERFLY VALVES

Tdk rubber lined butterfly valve is most economical here the entire flap is bonded with rubber and the body is also enveloped with rubber sleeve and hence no metal part comes in contact with the flow media.

THESE VALVES CAN BE USED FOR CORROSIVE SERVICE AT LOWER COST.

SIZES: 50 MM TO 600 MM

 

All TDK standard butterfly valve are available with following types of Actuation:

• Pneumatic Rotary Actuator
• Pneumatic Piston & Cylinder Arrangement

TDK DUAL PLATE CHECK VALVE

 

TDK Wafer Dseign Dual Plate Check Valve is general purpose check valve that performs all regular check valve duties. Yet it is lighter, smaller and therefore less expensive both to install and maintain  than  the  conventional  check  valve The unique design feature of TDK DUAL PLATE CHECK VALVE is that neither pressure nor flow is required to  center  the  disc/plate    against  the  sealing surface to effect a seal  thus  can  be  mounted on  horizontal  or Vertical pipe line. 

 

Salient features

  • POSITIVE SEATING ACTION BY TORSION SPRING
  • LIGHT WEIGHT  & COMPACT DESIGN
  • EASE OF INSTALLATION (HORIZONTAL/VERTICAL)
  • MAXIMUM OPENING & LESS PRESSURE DROP
  • 100 % LEAK PROOF AT LOW PRESSURE
  • SIMPLIFIED PIPING LAYOUT
  • SUITABLE FOR HIGH TEMPERATURE AND PRESSURE

 SIZE RANGE - 2"-36". (50MM - 900MM)

TDK WAFER SWING CHECK VALVE 

TDK WAFER SWING CHECK VALVE provides all the benefits of backflow prevention with extremely compact Construction & availability in corrosion resistant material.An Elastomer seal in the body gives a positive shut-off even at low differential pressures. The seal is preferentially located in the body out of flow path ensuring long operating life.A variety of elastomers are avaliable to suit operating conditions. 

The WAFER SWING CHECK VALVE is suitable for mounting in Horizontal & vertical pipeline with flowupwards & is provided with eyebolt for ease of installation.

 The WAFER SWING CHECK VALVES fits inside the bolt circle of adjoinning flanges and is suitable for installation between all flange assemblies.


 SIZE RANGE - 2"-36". (50MM - 900MM)

TDK AXIAL CHECK VALVE 


TDK AXIAL CHECK VALVE are used normally at delivery head of pump and are designed to close before the pump stops completely. This prevents immediate flow reversal and thus eliminates water hammer and sytem surges associate with valve closure. The size ranges from 2”tO 24”.

Salient features OF TDK AXIAL CHECK VALVE
  • Quite operation
  • Quick closure
  • Guided Discs
  • Vertical or Horizantal Installation
  • Metal to Metal & resilent seat avaliable

SIZE RANGE - 2"-12". (50MM - 300MM)
