Ball Valve – 2pc flange (soft seat)
Ball Valve – KHD-31, KHD-311, KHD-35
3pc ball valves offer in-line maintenance possibility, where combination of end connections offer great flexibility.
Three-piece ball valves composed of 3 separate pieces held together by bolts.
A three piece ball valve is preferred wherever regular cleaning is required.
The ball valve ends can remain threaded into the pipe, while the center section can be removed.
A butt weld ball valve contains a butt weld-sized connection for inlet and outlet connection.
The valve with butt welding end connection ensures no accidental leakage.
Threaded ball valves contain internal and external threads to facilitate inlet and outlet connections.
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-31 ball valve
No mounting pad PN50 / CL300
These valves are without an ISO mounting interface.
This means that you need a bracket and drive dog to mount the actuator to the valve.

Features
- Chevron stem packing reduces wear and increases sealing performance
- 3-piece swing-out design enables in-line maintenance
- Blowout-proof stem
- V-port options available in 10°, 30°, 60°, 90° for control applications
- Certified according to PED 2014/68/EU
- EN 10204-3.1 Material Certificate is complementary
Standards
- Inspection Standard: API 598, ISO 5208 or EN 12266-1
End Connection
- Threaded
- Buttweld, long buttweld
- Socketweld
- Combination of end connections also available
Temperature Range
- -4°F to 350°F (-20°C to 180°C) with PTFE seats
- -4°F to 400°F (-20°C to 200°C) with MG1241 seats
KHD-31 ball valve
KHD-311 ball valve
No mounting pad PN63
These valves are without an ISO mounting interface.
This means that you need a bracket and drive dog to mount the actuator to the valve.
3-piece ball valve
KHD-311 PN63, ¼" - 4" (DN8 ~ DN100)
Features
- Chevron stem packing reduces wear and increases sealing performance
- 3-piece swing-out design enables in-line maintenance
- Blowout-proof stem
- V-port options available in 10°, 30°, 60°, 90° for control applications
- Certified according to PED 2014/68/EU
- EN 10204-3.1 Material Certificate is complementary

End Connection
- Threaded
- Buttweld, long buttweld
- Socketweld
- Combination of end connections also available
Temperature Range
- -4°F to 350°F (-20°C to 180°C) with PTFE seats
- -4°F to 400°F (-20°C to 200°C) with MG1241 seats
KHD-311 ball valve
KHD-35 ball valve
ISO direct-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.
Direct-mount 3-piece ball valve
SIL3 Capable, ¼" - 4" (DN8 ~ DN100)
Direct-mount 3-piece ball valve, extended butt weld end
SIL3 Capable, ¼" - 4" (DN8 ~ DN100)
Direct-mount 3-piece ball valve, extended orbital weld end
SIL3 Capable, ½" - 4" (DN15 ~ DN100)
Features
- Square stem and twin ISO 5211 mounting pad allow easy automation
- Self-adjusting stem packing with Belleville washers minimizes need to re-tighten packing
- Chevron stem packing reduces wear and increases sealing performance
- 3-piece swing-out design enables in-line maintenance
- Blowout-proof stem
- Anti-static device(optional)
- V-port options available in 10°, 30°, 60°, 90° for control applications
