Ball Valves
Types of Hydraulic & Pneumatic Ball Valves
Ball valves are used for on/off isolation in hydraulic and pneumatic circuits. They are commonly selected where a quarter-turn valve provides simple operation and reliable shutoff.
- Ball valves used for isolating equipment during maintenance.
- Valves selected for low restriction and straightforward on/off control.
- Ball valves chosen to match the port/thread and sealing method used in the system.
For one-way flow control, compare Check Valves.
Key Selection Criteria for Ball Valves
- Pressure rating and temperature requirements for the system.
- Port size and connection standard compatibility.
- Seal and material compatibility with media and environment.
- Required handle style and installation clearance.
- Serviceability needs and operating frequency.
Selecting a properly rated ball valve supports reliable isolation and reduces leak risk during operation.
Frequently Asked Questions
When should I use a ball valve in a fluid power system?
Use a ball valve when you need simple on/off isolation, such as shutting off flow for maintenance or isolating a section of a circuit.
What should I confirm for pressure rating and port size?
Confirm maximum working pressure, port size, and the connection standard so the valve matches the system and maintains sealing compatibility.
How do I choose materials and seals for ball valves?
Match materials and seals to the media and environment, especially where temperature, corrosion exposure, or chemical compatibility affects long-term performance.
