3-way irrigation ball valves

Product Overview

This 3-Way T-Port Ball Valve is an essential component for professional irrigation systems requiring manual flow diversion. Designed for agriculture, greenhouse, and horticulture applications, it allows farm managers and engineers to manually control water flow from a single inlet to two separate outlets, mix two inlets to one outlet, or bypass a section entirely.

Unlike standard L-port valves which offer limited control, our T-port (Tee) design provides 360° handle rotation, enabling complex flow path management. The heavy-duty barbed connections ensure a secure, leak-proof fit with standard PE (poly) irrigation pipes. As a dedicated manufacturer of irrigation fittings, we ensure this valve is built from high-impact, UV-stabilized polypropylene (PP) to withstand harsh field conditions, chemical fertilizers (fertigation), and prolonged sun exposure.

Key Advantages:

• Multi-Function Control: 360° T-port for flow diversion, mixing, straight-through, or complete shut-off.
• Leak-Proof Seal: Deep barbed connectors provide high pull-out resistance (use of hose clamps recommended).
• Chemical & UV Resistant: Constructed from durable PP and POM materials for long service life.
• Easy Operation: High-visibility red handle with low-torque, smooth operation.

How the 360° T-Port Valve Works: One Valve, Multi-Control

Our T-port valve offers superior versatility over simple on/off or L-port valves. The internal ‘T’ shaped channel can be rotated 360° to create multiple distinct flow paths for precise control:

1. Straight Flow: Allows water to pass directly through the main line, bypassing the side outlet.
2. Divert Flow (90° Turn): Rotates to divert 100% of the flow from the main inlet to the side outlet.
3. T-Flow (All Ports Open): Allows water from the inlet to split and flow to both outlets simultaneously.
4. Closed Position: The handle position (often indicated by an arrow as “points to closed”) blocks flow to one or all ports, depending on the rotation.

This multi-control capability allows a single valve to manage complex tasks, such as switching between two irrigation zones or bypassing a filtration system for maintenance.

Technical Specifications

Applications in Agricultural & Greenhouse Systems

Designed for heavy-duty use, this valve is the ideal solution for:

• Zone Control: Manually switching irrigation between two different zones or drip lines.
• Bypass Lines: Installing a bypass for filtration systems or fertilizer injectors (Venturi), allowing for easy maintenance.
• Flow Diversion: Diverting water from a main line to a sub-line or storage tank.
• Greenhouse Management: Controlling flow to different benches or nutrient solution tanks (fertigation).
• System Draining: Can be used at low points in the system as a flushing or drain valve.

Installation & Compatibility

• Pipe Compatibility: Designed for standard PE (Polyethylene) irrigation pipes (LDPE or HDPE) of 16mm, 20mm, or 25mm nominal sizes.
• Installation Guide:
  1. Ensure a clean, square cut on the PE pipe.
  2. If the pipe is rigid, gently warm the end in hot water (do not use flame).
  3. Push the pipe firmly over the barb until it covers all barbs and seats against the valve body.
  4. Crucial: For all pressures, especially above 2 bar (30 PSI), secure the connection using a suitable Hose Clamp (Ratchet Clamp or Stainless Steel Clamp) to prevent blow-offs.

Frequently Asked Questions (FAQ) for Procurement

Q1: What is the main difference between your T-Port valve and a cheaper L-Port valve?

A: An L-Port valve typically only allows diversion from one inlet to another (90° turn) or shut-off. Our T-Port (Tee-Port) valve allows for 360° control, enabling diversion, mixing, or straight-through flow, providing far greater system flexibility (as shown in our diagram).

Q2: Is this 3-way valve UV resistant? How long does it last in the field?

A: Yes. The valve body is made from UV-stabilized polypropylene. It is designed to last 5-7+ years in direct sunlight, though lifespan varies with climate and chemical exposure.

Q3: Is a hose clamp necessary for the barbed connection?

A: Yes, we highly recommend it. While the barbs provide a tight fit, temperature fluctuations and water pressure (especially water hammer) can cause pipes to slip. A hose clamp ensures a reliable, long-term, leak-proof connection, especially at the rated PN6 pressure.

Q4: What is your working pressure (PN) rating?

A: This valve is rated for a maximum working pressure of 6 Bar (PN6) or 87 PSI.

Q5: Can I get samples to test before placing a bulk order?

A: Absolutely. We encourage engineers and distributors to request samples. Please contact our sales team to arrange sample shipping.

Q6: What is the MOQ for the 16mm barbed valve?

A: Our MOQ varies by production run. Please “Request a Quote” below, specifying your required sizes and quantity, and we will provide a detailed quotation.
