Internally Piloted Valve FAQ
What maintenance is required for Internally Piloted Valves?
Internally Piloted Valves require minimal maintenance due to their robust design. Regular inspections should include checking for leaks, verifying proper operation, and monitoring system pressure. The recommended maintenance interval is every 2,000 operating hours or annually, whichever comes first. Seal replacement may be needed after approximately 5,000 operating hours depending on operating conditions.
Can Internally Piloted Valves be used with aggressive media?
Yes, Internally Piloted Valves can handle aggressive media when equipped with appropriate seal materials. Standard models come with NBR seals suitable for most industrial applications. For aggressive chemicals or high-temperature applications, FKM or EPDM seals are available. Special material options include stainless steel bodies for corrosive environments. Always consult the chemical compatibility chart for your specific media.
How does an Internally Piloted Valve differ from other valve types?
Internally Piloted Valves use an integrated pilot mechanism to control the main valve operation, resulting in more precise flow control with less hysteresis compared to direct-operated valves. The internal pilot system allows for higher flow capacities at lower pressure drops while maintaining consistent performance across the entire operating range. This design also reduces wear on moving components, leading to longer service life.
Installation Guidelines
- Ensure the system is depressurized before installation
- Verify flow direction matches valve markings
- Use proper thread sealant on connections (avoid Teflon tape for hydraulic applications)
- Torque connections to manufacturer specifications
- Protect valve from particulate contamination during installation
- Perform initial operational test at reduced pressure
