Ball Valves

Ball Valves

Choose from a variety of product offerings within 15 categories of valve types:

Ball Valves: designed primarily for on/off service. These valves contain a ball with a hole through it. A handle or electric actuator rotates the ball 90°, turning the flow on or off. Use plastic ball valves for
liquids only; metal valves for liquids or gases.

Check Valves: self-actuated valves designed to prevent fluid from flowing backward into your system. Flow forces a ball or disk in one direction to open the valve; when flow stops, the ball or disk seats to close the valve.

Diaphragm Valves: use a flexible diaphragm to shut off flow—center of the diaphragm is pushed down into a seat. Use these valves for fluids that are dirty or have a high particulate content.

Elliptical Valves: similar to ball valves except elliptical valves use an elliptic O-ring to seal the cylinder during rotation. The seal design makes these valves ideal for vacuum applications.

Metering Valves: multi-turn valves designed to regulate the flow of fluid. These valves generally have low flow rates and high pressure differentials.

Needle Valves: feature the most accurate flow control among the valves we offer. They are an excellent choice for precise metering of liquids or gases.

Pinch Valves: squeeze shut a piece of tubing. Fluid contacts only the tubing—ideal for your high-purity fluid applications.

Plug Valves: used primarily for on/off service. Controls flow using a plug with a hole through it. Plugs can be made of rigid materials such as PTFE, making them ideal for high-purity applications.

Pressure Valves: designed to control or limit pressure—not flow—in a system. These self-actuating valves will either open a relief port or bypass the fluid when a preset limit is reached.

Proportioning Valves: designed to produce variable flow rates. Valves open and close in proportion to the signal from your controller.

Sample Valves: special three-way valve designed to tap off a portion of the main flow for sampling purposes.

Sanitary Valves: commonly feature Tri-Clamp® connections and 316 stainless steel body construction for sanitary and high-purity applications.

Solenoid Valves (Direct Lift): use a plunger that is actuated to open or close the fluid path. They generally have quicker response time than pilot-operated valves.

Solenoid Valves (Air Controlled): utilize pressure created by air or liquids for actuation purposes. These valves are either piston or diaphragm types and require differential pressure to keep valve closed. Because they don’t have a plunger, they are usually available in larger orifice sizes than direct lift
valves.

Stopcocks: similar to ball valves except stopcocks are much smaller in size. Primarily used in the laboratory for on/off control of flow or as a crude regulation of flow rate.
