Feature → Business Impact → Application: The 2/2 diaphragm valve design enables bidirectional shutoff with reliable, fail-safe operation in pneumatic circuits, delivering precise flow control and reducing leakage risk in high-cycle lines. This translates to measurable uptime gains in packaging, material handling, and automated assembly, while supporting compliance with process stability requirements. Feature → Business Impact → Application: Dampened operation minimizes mechanical shock and wear on valves and actuators, extending service life and reducing maintenance costs in wash-down environments or outdoor installations. This is especially valuable in beverage, pharmaceutical, and automotive assembly lines where valve longevity directly impacts total cost of ownership. Feature → Business Impact → Application: Click-on coil interchange allows tool-free coil changes, slashing maintenance time during preventive service and fault response, which boosts line availability and reduces labor costs in OEM projects. Feature → Business Impact → Application: Stainless steel body (DIN 1.4408 / AISI 316) and NBR seat seal provide corrosion resistance and reliable sealing, supporting long-term performance in humid, dusty, or wash-down environments, such as metal stamping or palletizing cells. Feature → Business Impact → Application: IP65 ingress protection ensures reliable operation in dirty environments and exposed installations, reducing failure modes due to moisture or dust and easing compliance with plant protection standards. Feature → Business Impact → Application: Operating range -10 to 50 °C and 0 to 10 bar allows use across diverse pneumatic networks, minimizing part diversity and simplifying inventory for manufacturers deploying multi-site systems.

FAQs
Install the valve in a straight-through flow path matching the G1 port specification. Align the valve orientation with the intended flow direction, ensure compatible electrical coil (9151) is used, and secure with appropriate fittings. The unit supports tool-free coil interchange, enabling quick field servicing without disassembly. Verify IP65 protection is intact after installation to maintain environmental sealing.
The valve operates from -10 to 50 °C and supports pressures from 0 to 10 bar. It uses a stainless steel body and NBR seat seal, delivering reliable performance across a wide range of industrial environments while maintaining stable shutoff and flow control.
Yes. The 2/2 diaphragm design provides a high flow rate with damped operation to minimize wear, making it suitable for demanding manufacturing lines, packaging, and material handling where consistent actuation under fluctuating pressure is essential.
The valve is IP65 rated, providing protection against dust and water jets for reliable operation in harsh environments. This rating supports use in wash-down zones and outdoor installations typical of factory floors and process lines.
Damped operation reduces mechanical stress and extends valve life, lowering replacement and maintenance costs. Tool-free coil interchange minimizes downtime during preventive maintenance or coil faults, accelerating repairs and boosting overall line availability and return on investment.
