Full Welded Ball Valves Handle Operated - China Suppliers & Factory for Reliable Flow Control Solutions
Product Details
Inside the valve body, a perforated ball with multiple channels aligns with specific ports depending on the rotation of the handle or actuator.
There are three types of three-way ball valves: T-type, L-type and Y-type.
1. T-type and Y-type three-way ball valves can make three orthogonal pipelines connected to each other and cut off the third channel, which can play the role of diversion and merging.
2. L-type three-way ball valves can only be connected to two pipelines that are orthogonal to each other, and can't keep the third pipeline connected to each other at the same time, but only to play the role of distribution.
Three-way ball valves can be threaded or flanged. Our 3 way flanged ball valves are most the panel mount 3 way ball valves with ISO5211 mounting pad, which can be easily equipped with pneumatic or electric actuators for your remote control applications.
★ Key Features
● One-Piece Welded Body
● Superior Seal Performance
● Multiple Actuation Options
● Flexible Connection & Bore Options
✓ Standard Test
Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test: On request, any other test can be carried out according to special instruction by client.

Frequently Asked Questions
Q What are the three types of three-way ball valves and how do they differ?
The three types are T-type, L-type, and Y-type. T-type and Y-type valves allow three orthogonal pipelines to connect simultaneously and can divert or merge flow. L-type valves connect only two orthogonal pipelines at a time and are used primarily for flow distribution, not simultaneous three-way connection.
Q What connection types are available for three-way ball valves?
Three-way ball valves are available in both threaded and flanged connection types. The flanged versions typically feature an ISO5211 mounting pad, making them compatible with pneumatic or electric actuators for remote control applications.
Q What materials are used in the construction of these ball valves?
The main components such as the body, ball, and stem are made from SS316 or SS304 stainless steel. Sealing parts including the seat, stem gasket, and packing are made from PTFE for excellent chemical resistance and low friction. Other hardware components use SS304 or SS201 stainless steel.
Q What pressure tests are performed on these ball valves before shipment?
Each valve undergoes a Body Test at 1.5 times the working pressure with water, a Seat Test at 1.1 times the working pressure with water, and a Function/Operation Test to verify correct open/close operation of the valve and actuator assembly. Special tests can also be arranged upon client request.
Q Can these valves be automated with pneumatic or electric actuators?
Yes. The flanged three-way ball valves feature an ISO5211 mounting pad, which allows easy installation of pneumatic or electric actuators. They are compatible with accessories such as solenoid valves, limit switches, and air filter regulators for full automation and remote control.
Q What size range is available for these three-way ball valves?
The valves are available in sizes ranging from DN25 (1 inch) up to DN350 (14 inches), covering a wide range of industrial pipeline applications with corresponding face-to-face lengths, bore diameters, and overall heights as listed in the dimensions table.
