Ball valves are quarter-turn valves for isolation and selected control duties. The current Trekre range includes flanged, threaded, welded, multi-port, manual, worm-gear, pneumatic, electric, lined, metal-seated, V-port, vacuum, and discharge configurations; final selection depends on the specific service.

Trekre Ball Valves Series

What Is a Ball Valve?

A ball valve is a quarter-turn valve that uses a bored ball, stem, and seats to control flow. Turning the stem rotates the ball between open and closed positions. Ball valves are commonly used for isolation, and selected designs can also support diversion, mixing, or controlled-flow duties.

Ball Valve Types Available

The current Trekre Ball Valves category includes these verified product types and configurations:

Flanged ball valves, including ANSI, JIS, KS, DIN and other product-specific flange designs.
Threaded ball valves and welded three-piece ball valves.
Three-way and four-way ball valves for product-specific routing duties.
Pneumatic, electric, manual, and worm-gear operated configurations.
Lined ball valves, metal-seated ball valves, V-port regulating ball valves, vacuum, and discharge configurations.

Ball Valve Materials

Current product titles identify stainless steel, carbon steel, cast steel, and CF8-based configurations. Some products identify PTFE in the product title or a lined construction. The body material, ball/trim arrangement, seats, seals, and lining must be reviewed as a complete valve design; material names alone do not confirm temperature, pressure, or chemical compatibility.

End Connections and Operation

The current range includes flanged, threaded, and welded connection options. Product-specific configurations include manual handles, worm gear operators, pneumatic actuators, and electric actuators. Select the connection, bore, operating mode, and control function to suit the installation and service requirements.

How to Select a Ball Valve

Medium and any chemical compatibility requirements
Operating and design pressure and temperature
Valve size, required bore, and shutoff requirement
Body material, seat material, seals, and any lining requirement
Flanged, threaded, or welded connection; applicable flange or piping standard
Two-way isolation, multi-port flow routing, or regulating duty
Manual, worm-gear, pneumatic, or electric operation
Flow direction and any required inspection or documentation

Confirm the final selection against the product datasheet and order specification for the actual valve series.

Typical Applications

Ball valves can be used in industrial fluid systems for isolation and, where the selected design supports it, routing or controlled-flow duties. Typical suitability depends on the medium, material selection, connection, actuation, pressure, temperature, and site requirements. Do not treat a general category page as a universal service recommendation.

Standards and Testing

Current product titles reference ANSI, JIS, KS, and DIN configurations. Available standards vary by valve design and product series; they are not a claim that every ball valve in this category meets every listed standard. Confirm the applicable datasheet, drawing, inspection scope, and order specification for the selected product.

FAQ

What is a ball valve?

A ball valve uses a rotating bored ball to open or close a flow path. It is commonly selected for isolation, with some product designs supporting routing or control duties.

What is the difference between a two-way and a three-way ball valve?

Two-way valves are generally used for a single flow path. Three-way designs have an additional port for product-specific routing or mixing arrangements; confirm the actual port configuration before selection.

How do I select ball valve seat material?

Review the medium, temperature, pressure, shutoff requirement, and the specific valve design. Seat material must be confirmed with the product documentation.

When should I use a full-port ball valve?

Required bore depends on the piping, flow requirement, pressure loss allowance, cleaning needs, and selected valve series. Confirm the bore with the relevant product drawing.

Can ball valves be automated?

Yes. The current category includes pneumatic and electric product configurations. Select the actuator according to required operation, control signal, torque, environment, and valve design.

What information is required when ordering a ball valve?

Provide the medium, pressure, temperature, size, connection, material and seat requirements, valve function, operating mode, applicable standard, and any inspection or documentation requirements.
