Features

• 1.316L Stainless Steel Construction: Exceptional corrosion resistance for harsh chemical, marine, and offshore environments, with wetted parts in stainless steel for extended service life

• 2.Diaphragm-Operated Design: Ensures bubble-tight shut-off even at low pressures, minimizing fluid loss and maximizing system efficiency

• 3.Ultra-Low Power Consumption: 3.5 W standard operation for energy savings in remote installations with limited power supply

• 4.Dual-Rated Explosion-Proof Certification: ATEX/IECEx II G Exd T6 (-50°C ≤ Ta ≤ +60°C) and T4 (-50°C ≤ Ta ≤ +80°C) as standard for Zones 1 & 2, Gas Groups IIA, IIB, IIC

• 5.1/4" NPT Porting: Standard 1/4" NPT female ports for easy integration with existing pipework and subplates

• 6.Broad Media Compatibility: Suitable for water, mineral oils, water glycols, methanol, and other non-corrosive fluids for versatile application flexibility

• 7.Ingress Protection: IP67 as standard (NEMA 6), with IP68 option available for third-party approval for submersible applications

• 8.Wide Temperature Range: Standard -50°C to +60°C, with high-temperature option (-20°C to +80°C) for extreme environments

• 9.Rapid Response Time: 10–15 ms actuation speed for precise flow control in dynamic hydraulic systems

• 10.Zero Pressure Rated: Operates reliably from 0 to maximum pressure without requiring minimum pressure differential

• 11.SIL Capable: Available with SIL2/SIL3 capability for safety-critical applications requiring third-party approval

• 12.Easy Maintenance: Dismountable without disturbing pipework for quick servicing and reduced downtime
