Description
The GRACO 512643 is a high-pressure ball valve designed for use in GRACO fluid handling equipment. It is constructed for durability and reliability, typically made from robust materials such as stainless steel or high-grade alloys, and is intended to control the flow of fluids in high-pressure systems up to 5000 PSI. Its primary function is to provide a secure shut-off and flow control in demanding industrial applications.
Key Features:
- Ball Valve
- 1/2 NPT (FB)
- 5000 PSI (35 MPa, 350 bar)
- Designed for GRACO high-pressure fluid handling equipment; compatible with systems requiring 1/2 NPT connections
- High-pressure rating suitable for industrial applications
- Reliable shut-off and flow control
- Durable construction for long service life
- Ease of maintenance (typical for GRACO ball valves)
Applications:
Used in industrial lubrication, hydraulic, and fluid transfer systems where high-pressure shut-off and flow control are required. Suitable for mining, agriculture, and other heavy-duty environments.
Installation Notes:
- Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
- Ensure the system is depressurized before installation
- Use appropriate thread sealant for NPT connections
- Tighten to recommended torque specifications
- Inspect for leaks after installation
- Regularly check valve operation and seals for wear
- Follow manufacturers installation guidelines
- Use only compatible fittings and accessories
- Perform routine maintenance checks
