3 Way Ball Valve Supplier in India

Krishna Industries (KELOR) supplies 3 Way Ball Valves from Ahmedabad, Gujarat. We stock both L-port (diverter) and T-port (mixer/distributor) configurations. Body materials include WCB, SS304 (CF8), SS316 (CF8M), and SS316L (CF3M).

Furthermore, we supply all end connection types — screwed BSP/NPT, socket weld, and flanged Class 150 and Class 300. Size range covers DN15 (½”) to DN200 (8″). All valves are API 598 tested. GST invoice included. MOQ is 10 Nos.

A 3 way ball valve combines flow diversion, mixing, distribution, and bypass in one compact body. As a result, it replaces two separate 2-way valves plus a tee fitting. However, you must specify the correct port configuration — L-port or T-port — before ordering. The wrong configuration cannot perform the required flow function.

L-Port vs T-Port — The Most Important Specification Decision

L-port and T-port are not interchangeable. The ball bore geometry decides which ports are connected at each valve position. Therefore, always confirm port type before raising the purchase order.

3-Way Ball Valve vs Two Separate 2-Way Ball Valves

Many engineers use two 2-way ball valves plus a tee for flow switching. However, a single 3-way ball valve is simpler, safer, and more compact. Here is a direct comparison.

Applications in Indian Industries

HVAC — 3-Way Mixing and Diverting Valves

T-port SS304 or WCB flanged Class 150 DN25–DN100. Used for chilled water coil bypass and supply/return blending. Furthermore, electric actuation with BMS signal enables automatic temperature control. Consequently, this is the standard 3-way mixing valve in Indian commercial buildings, hotels, and hospitals.

Chemical Plants — Ankleshwar, Vapi, Dahej

L-port SS316 screwed BSP or flanged Class 150 DN15–DN80. Switches chemical feed between main drum and backup. Also used for diverting process lines to sample collection. Pneumatic actuated with spring return for process automation. L-port ensures only one destination is active at a time.

Pharmaceutical Utility

T-port SS316L CF3M flanged Class 150 DN25–DN80. Mixes purified water (PW) with hot water for temperature-controlled loops. Additionally, it mixes clean steam and cold PW for warm water utility. Pneumatic actuated with position feedback to DCS. SS316L CF3M satisfies GMP documentation requirements.

Water Treatment — ETP and STP

L-port WCB or SS304 flanged Class 150 DN50–DN150. Switches chemical dosing between two dosing points. In addition, it diverts process streams to different treatment stages. Finally, lever operation allows manual switching during routine plant operation.

OEM Process Equipment Skids

L-port or T-port SS316 screwed BSP DN15–DN50. Replaces two 2-way valves and a tee in compact skid design. As a result, a single pneumatic actuator eliminates sequencing logic. Standard for Indian OEM manufacturers in Pune, Ahmedabad, Coimbatore, and Hyderabad.

Boiler Feed and Steam Distribution

L-port WCB flanged Class 150/300 DN25–DN100. Switches boiler feed water between two boilers from one feed pump. Moreover, it handles steam header switching and condensate return diversion. Since WCB body tolerates steam and condensate, no special lining is required. Lever operated for manual control.

• Four Way Ball Valve — L-port and X-port 4-port configuration — for cross-connection and heat exchanger flow reversal requiring four pipe connections
• SS Ball Valve — 2-Way — standard on/off isolation in the same SS piping where 3-way handles switching and mixing
• WCB Globe Valve — throttling and flow control — use globe valve for flow rate, 3-way for flow path selection
• Pneumatic Ball Valve — 2-Way — automated on/off isolation alongside pneumatic 3-way switching valves
• Y Strainer — install upstream on all inlet connections — protects PTFE seats and ball surface from particle damage

Frequently Asked Questions

1. How do I decide between L-port and T-port?

First, ask this question: do two inlets or outlets need to connect simultaneously at any point? If yes, specify T-port. If only one destination is active at a time, specify L-port.

For example, for tank switching (pump to tank A or tank B, never both): specify L-port. For HVAC temperature blending (hot and cold water mixed together): specify T-port. Similarly, for source changeover (main to backup, one at a time): L-port. When in doubt for simple switching, L-port is more common and easier to automate.

2. Can a 3-way ball valve throttle flow?

No. A 3-way ball valve is an on/off switching valve only. In the partially open position, high velocity flow erodes the PTFE seat and scores the ball surface rapidly. Therefore, always operate it fully at 0° or fully at 90°.

For varying the ratio of hot to cold water in blending, a 3-way globe valve or modulating control valve is the correct specification. The 3-way ball valve switches between defined flow paths — it does not modulate flow proportion.

3. Why does a 3-way ball valve need a higher actuator torque than a 2-way?

A 3-way ball valve has three port openings instead of two. As a result, more ball surface area contacts differential pressure during switching. This increases operating torque significantly.

Therefore, always provide the valve torque data sheet to the actuator supplier. Never use a 2-way valve torque estimate. Otherwise, undersized actuators cause incomplete valve travel and incorrect flow path selection on site.

4. Is spring return always needed on a pneumatic 3-way actuator?

Spring return is needed when the process requires the valve to return to a safe position on air failure. For instance, an L-port diverting between process and drain needs spring return to process position. This prevents unintended line drainage if air supply is lost.

Similarly, a T-port on HVAC mixing needs spring return to straight-through. This prevents coil freeze-up in cold weather. On the other hand, double acting is correct for non-safety-critical automation. In that case, air failure position is not a safety requirement. Always define the fail-safe position — position 1 or position 2 — when ordering.

5. What is the MOQ?

MOQ is 10 Nos. Moreover, we supply project and OEM orders of 10 to 500+ Nos. Documents include API 598 test certificate, MTC, dimensional report, and GST invoice.
