The brass body delivers robust corrosion resistance in demanding process streams, reducing maintenance costs and downtime in critical piping networks. The combination of brass with a PTFE seat seal ensures reliable shut-off across a wide chemical range, lowering leak-related risks in both clean and contaminated fluids. In practice, this translates to longer service life and predictable performance in automated plants, from food-grade to chemical processing lines. Damped closing minimizes hydraulic shocks and reduces wear on seals, while back-pressure tightness guards against reverse flow in fluctuating upstream conditions. Together, these features support stable process pressure and safer startup/shutdown sequences, particularly in systems with long piping runs or pulsed demand. This improves overall system efficiency and reduces valve chatter in dynamic applications. The PTFE seat seal offers broad chemical compatibility, tolerating contaminated fluids and entrained particulates that would damage lesser seals. The design suits mixed-media lines where particulate load can challenge valve performance, providing dependable shut-off even when filtration is imperfect. Compatibility with gas and liquid media makes it a versatile choice for plant-wide valve automation. Configured as a normally closed 2/2 valve with G1 port, it provides straightforward control from simple solenoid pilots or liquid pilot signals in compact installations. The compact 120 x 200 x 80 mm footprint and brass body simplify integration into existing manifolds and bracketed layouts. Maintenance remains straightforward thanks to modular seals and standard spare parts. Its wide operating range (-10 to 180 C, 0 to 10 bar) supports multi-site process automation without frequent part changes, while the G1 port aligns with common automation hardware. Mounting flexibility and standardized dimensions help minimize revision work during retrofit projects. In practice, installers value the predictable performance and availability of genuine spare parts in industrial environments. For reliability, the valve family benefits from proven spare parts availability and robust supply chains, ensuring quick replacements and reduced downtime in critical production lines.

FAQs
The valve features a standard ISO G1 parallel threaded port. When wiring and piping, pair it with compatible G1 female connectors and compatible seals to maintain pressure integrity. Always verify thread tolerance and torque specifications from the datasheet when retrofitting into an existing manifold.
This model operates from -10 to 180 degrees Celsius and supports pressures from 0 to 10 bar. This broad range makes it suitable for diverse media, including gases and liquids, while maintaining tight shut-off and long seal life in dynamic process lines.
Yes. The PTFE seat seal provides broad chemical compatibility and resilience against particulates, helping maintain reliable shut-off even when filtration is imperfect. For extreme particulate loads, consider upstream filtration or a brief inspection routine to ensure continued performance.
The valve is a 2/2 normally closed device that can be actuated by solenoid pilots or liquid pilot signals. Its compact G1 port and standard dimensions simplify integration with existing control cabinets and pilot assemblies in automation racks.
Use genuine seals and spare parts designed for this model; the PTFE seat and brass body are designed for longevity. Schedule periodic inspections, replace seals at maintenance intervals, and stock standard spare parts to minimize downtime during planned or unplanned maintenance.
