FAQs
The valve uses a standard G1/2 port size, enabling straightforward mounting to common manifolds and fittings. Its compact geometry and 140 mm length with 70 mm height facilitate integration into tight automation panels and field installations, reducing the need for adapter fittings and saving assembly time.
This valve operates from -10 to 60 °C (14 to 140 °F) and supports pressures from 0 to 16 bar (0 to 232 psi). The 2/2 NC configuration provides normally closed operation, ensuring safe shutoff under loss of control power or during valve cycling in low-pressure systems.
Yes. The design accommodates contaminated flow fluids and is rated for vacuum applications up to 90%—useful in conveying, transfer, and vacuum-assisted processes. The PTFE seat seal enhances chemical compatibility, while dampened closing minimizes disturbances in backflow-prone or sensitive lines.
Certification readiness depends on configuration and regional requirements. CE marking, IP protection ratings, and SIL options may be available for specific variants; consult the datasheet and supplier specifications to confirm applicable certifications for your installation.
The visual position indicator accelerates commissioning and fault diagnosis, reducing downtime. The brass body with PTFE seat offers durable chemical resistance, while dampened closing reduces wear and water hammer, collectively extending service life and lowering maintenance costs over the valve’s lifetime.
