The stainless steel pneumatic three-way T-type diaphragm valve is designed for flow diversion and confluence control in sanitary and industrial piping systems. The T-port configuration allows one inlet to connect two outlets — or two inlets to merge into one — without cross-contamination between flow paths. This makes it a standard choice in food processing, pharmaceutical production, biotechnology, and chemical handling where media separation and hygienic operation are required.
KONTE manufactures this valve series with CF8 and CF8M stainless steel bodies, covering sizes from DN6 to DN100 and pressures up to 1.6MPa. The pneumatic actuator is available in single-acting or double-acting configurations to suit your automation and fail-safe requirements. As a direct valve manufacturer and exporter, KONTE offers OEM/ODM production, custom sizing, and bulk wholesale supply.

T-Type Three-Way Flow Path
The T-port internal geometry supports both flow splitting and flow merging in a single valve body. This eliminates the need for two separate two-way valves and one tee fitting, reducing pipe joints and potential leak points.
CF8 / CF8M Stainless Steel Body
CF8 (304 SS equivalent) suits standard water and food-grade media. CF8M (316 SS equivalent) adds molybdenum for resistance to chlorides and mild acids, covering a broader range of chemical and pharmaceutical applications.
PTFE, RPTFE, and PPL Diaphragm Options
The diaphragm is the only wetted moving part. PTFE handles most media and meets FDA material standards. RPTFE (reinforced PTFE) extends diaphragm service life under higher pressures. PPL suits high-temperature steam applications up to 180°C.
Multiple Actuator and Control Options
Single-acting spring-return actuators provide fail-safe NC or NO positions on air loss. Double-acting actuators deliver higher torque output for larger sizes. Manual override is available for maintenance and commissioning without compressed air.
Three Connection Standards
Welded (BW), tri-clamp (TC), and flanged ends are all available on the same valve series. This allows direct integration into hygienic tubing systems or standard flanged pipework.
Wide Temperature Range
Media temperature coverage from -20°C to 180°C handles hot water-for-injection (WFI) loops, steam-in-place (SIP) cycles, and cold media in one valve design.
The pneumatic three-way T-type diaphragm valve is used wherever a piping system needs automated flow direction control with hygienic or chemical-resistant requirements:
Pharmaceutical & Biotech — WFI distribution, CIP/SIP loops, buffer preparation, fermentation feed lines
Food & Beverage — dairy processing, juice filling, brewery piping, sauce and seasoning lines
Chemical Processing — multi-stream mixing, reagent dosing, solvent routing
Water Treatment — filtration bypass circuits, chemical dosing manifolds
Cosmetics & Personal Care — emulsion batching, cream filling systems

Q: What is a T-type diaphragm valve and how does it differ from a standard two-way diaphragm valve?
A: A standard diaphragm valve has one inlet and one outlet — it opens or closes a single flow path. A T-type three-way diaphragm valve has three ports arranged in a T configuration. It can direct flow from one port to either of the other two, or combine flows from two ports into one. This enables flow diversion or merging without additional fittings.
Q: Is this valve suitable for CIP and SIP service in pharmaceutical plants?
A: Yes. The CF8M body and PTFE/RPTFE diaphragm are compatible with standard CIP chemicals (caustic, acid, sanitizer) and SIP steam temperatures. Tri-clamp connections allow fast disassembly for inspection. Confirm your specific cleaning protocol temperatures with our technical team.
Q: What is the difference between single-acting and double-acting pneumatic actuators?
A: Single-acting (spring-return) actuators use compressed air to move the valve in one direction and a spring to return it on air loss — providing a defined fail-safe position. Double-acting actuators use air pressure in both directions for higher force output but have no automatic fail-safe unless a spring-return unit or solenoid with memory is added.
Q: Can KONTE supply the valve with a specific flange standard such as DIN or ANSI?
A: Yes. Flanged end connections are available to DIN, ANSI, and JIS standards. Specify your required standard, pressure class, and size when requesting a quote.
Q: What sealing material should I choose for steam service?
A: For steam and high-temperature media up to 180°C, PPL (polypropylene-lined) diaphragms are recommended. PTFE is suitable for temperatures up to approximately 150°C in continuous service.
