Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang LEGRIS dari 3G Electric.
What is the maximum operating pressure for LEGRIS lockout valves like the 7886 series?
LEGRIS compressed air line lockout valves in the 7886 series, such as MPN 7886 11 11 and 7886 22 22, are rated for a maximum operating pressure of 145 psi (CWP). This rating applies to both NPT and BSPP port configurations. The valves are designed for use with tube fittings and provide positive shutoff for lockout/tagout procedures on pneumatic systems.
Are LEGRIS miniature flow control valves like the 7665 04 10 suitable for meter-out or meter-in applications?
The LEGRIS miniature elbow-style flow control valve MPN 7665 04 10 is configured for meter-out control. This means it regulates the exhaust flow from an actuator, controlling speed during the return stroke. The valve body is made of technical polymer and accepts 4 mm tubing. For meter-in applications, a different valve orientation or model would be required.
What materials are used in LEGRIS nylon ball valves such as the 7915 series?
LEGRIS manual two-way ball valves in the 7915 series, including MPN 7915 56 11 and 7915 60 14, feature a nylon body with a lever handle. The valve is straight with push-to-connect (push) on one port and male NPT (MNPT) on the other. The full port ball provides unrestricted flow, and the maximum pressure rating is 145 psi (CWP). These valves are suitable for use with compressed air and other compatible fluids.
Can LEGRIS brass ball valves like the 0492 07 17 be used with water or oil?
The LEGRIS manual two-way ball valve MPN 0492 07 17 has a nickel-plated brass body and FNPT x FNPT ports. While it is commonly used in pneumatic systems, the nickel-plated brass construction provides corrosion resistance suitable for water and certain oils. However, you should verify compatibility with the specific fluid, temperature, and pressure conditions of your application, as the valve is rated for general industrial use.
What is the difference between LEGRIS lockout valves in the 7880 and 7886 series?
The LEGRIS 7880 and 7886 series are both compressed air line lockout valves, but they differ in port configuration and body style. The 7880 series (e.g., MPN 7880 10 17) uses BSPP threads, while the 7886 series (e.g., MPN 7886 11 11) uses NPT threads. Both are rated for 145 psi maximum operating pressure and are designed for tube fittings. The choice depends on the thread standard required for your piping system.
