Ball Valve – KHD-LB

These spark tested, fully PFA/FEP lined ball valves with integral ball and stem, offer most reliable protection from corrosive media.

Lined ball valves with PFA lining are suitable for high corrosive media in chemical industry such as
sulfuric acid, hydrochloric acid, caustics, pharmaceutical applications, and semicondoctor applications with ultra-pure water.
Due to its design nature, lined ball valves can also be used in vacuum applications.
With these features, lined ball valves exhibit replacement to special-alloy valves in high corrosive applications.

In general, soft seats are made of thermoplastic materials such as PTFE.
They are ideal for applications where chemical compatibility is important and where the tightest possible seal is essential.
However, soft seats are not recommended for dirty or abrasive process fluids.
Soft seats can break under these conditions, causing leaks in the valve.

KHD-LB ball valve
ISO direct-mount / ISO regular-mount

A direct mounting flange according to ISO 5211 is standard for these ball valves.
This feature allows an actuator to be mounted without the need for a mounting bracket and drive adapter.
This results in a significant cost reduction, a compact automated unit, and a higher level of safety for operators.

The ISO regular-mounting pad accepts direct mounting of pneumatic and electric actuators.
ISO 5211 is a European standard that specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.

PFA lined ball valve - DIN PN
DIN PN 16, ½" - 8" (DN15 ~ DN200)

PFA lined ball valve - ISO CLASS
ANSI CLASS 150, ½" - 8" (DN15 ~ DN200)
ANSI CLASS 300, ½" - 8" (DN15 ~ DN200)

PFA lined tank bottom ball valve - DIN PN
DIN PN 16, 1/1½" - 3/6" (DN25/40 ~ DN80/150)


Features

  • PFA lining offers highest corrosion resistances.
  • Bubble tight shut-off, precision machined ball and seats guarantees absolute leak free valve.
  • Full bore offers high KV value equal to the pipeline.
  • One piece ball-stem design, no possibility of damaging PFA lining on ball due to stem movement.
  • All lining parts must pass spark test with 15KV high voltage, to ensure no air pathway within lining parts.
  • Integral mounting pad design ensure no external force exerted on packing or valve top cap position, which leads to enlargement and inconsistency of valve output torque.
  • Insvestment casting body construction, ensure smooth body surface with minimum machining work.

Technical Data

  • Temperature: -29°C TO +180°C
  • Pressure Range: ANSI CLASS 150 / DIN PN16
  • Flange Connections: ANSI CLASS 150 / DIN PN16
  • Operator: lever / gear / pneumatic / electric actuators

Standards

  • EN10204- 3.1 material certificate available.

High Corrosion Resistance and High Durability

  • KLINGER KHD-LB lined ball valve provides excellent corrosion resistance in industrial applications. It has good chemical stability, high corrosion resistance, low rubbing modulus, and self-lubricate features, which is suitable for alkali and acid applications in semi-conductor manufacturing process, gas, and pharmaceutical applications.
  • The valve body is designed with stem-ball one-piece design for better molding of PFA lining material. With stem and ball assembled together, contact between ball and stem is eliminated, thus, provides strong body strength against media flow.
  • With genuine DAIKIN NEOFLON PFA raw material, KLINGER KHD-LB lined ball valve is able to operate under 150°C and 10 Bar working conditions. Other lining materials are available upon request for different purposes.

Seal Effects

  • With patterned design, KLINGER KHD-LB PFA lined ball valve offers perfect stem seal.
  • Multiple seal structure prevent leakage to minimum. The first sealing comes through thrust washer for tight sealing effect. The second sealing is V-shape structure packing system with flexible feature. The more pressure comes from valve bore, the more tightened it will become. For high demanding requirements, spring set is used to uniformly compresspacking downward for actuator applications.

Spark Test

  • During production, the liner integrity of each liner component is checked by using an electrostatic discharge "spark" tester. The entire lined surface is tested at a voltage of 15kV to identify any voids, cracks or pinholes that indicate gasket rupture.

Material Selections

  • KLINGER KHD-LB lined ball valve provides PFA and FEP lining material to fit different needs.
  • PFA has alkoxy substitutes in which it can be melt-processed. However, it also differs from a molecular level as it has a smaller chain length than other fluoropolymers. It is extremely durable which makes it suitable for use in demanding application. It is also the preferred option when it comes to choosing a material that requires high chemical resistance as well as high purity and low stiffness while it is also extremely durable when it comes to resisting weathering. It has a lower melting temperature when compared to PTFE while it has great insulation properties and is UV resistant which also adds to its durability.
  • All PFA material made with DAIKIN Neoflon PFA AP-230 in accordance with FDA requirement.
  • FEP has non-stick properties which again makes it suitable for use in applications where residues or oils are likely. FEP does have a softer makeup when compared to that of PTFE and that means that it can melt at a lower temperature which means that it is not suitable in applications that are exposed to high temperatures. Along with this, it is also transparent while it is resistant to sunlight and UV which makes it suitable for use in applications that are exposed to the elements.
