Features

• 1.316L Stainless Steel Construction: Exceptional corrosion resistance for harsh chemical, marine, and offshore environments, conforming to NACE MR-0175 for sour gas applications

• 2.Direct-Acting 3/2 Valve Design: Provides reliable control of pneumatic actuators with normally closed (NC), normally open (NO), or diverter (universal) functions

• 3.Hazardous Area Certification: II 2 G Exd IIC T6 (-50°C ≤ Ta ≤ +60°C) and optional T4 (-50°C ≤ Ta ≤ +80°C) dual-rated for Zones 1 & 2 (Gas Groups IIA, IIB, IIC)

• 4.High Ingress Protection: IP67 as standard (NEMA 6 equivalent), with IP68 option available for third-party approval

• 5.Compact Port Size: 1/4" NPT (DN10) connections for seamless integration with standard industrial pneumatic circuits

• 6.Dual Operation Modes: Spring return (monostable) and manual override/reset options for flexible system integration and fail-safe requirements

• 7.Low Power Consumption: 3.5W standard operation for energy-efficient performance in remote installations

• 8.Zero Pressure Rated: Operates reliably even at vacuum conditions, ensuring consistent performance across a wide range of applications

• 9.Multiple Seal Options: EPDM and Fluorocarbon (FKM) standard, with custom materials available for specific media compatibility

• 10.SIL Capability: SIL2 capable (in-house assessment) with optional SIL3 third-party approval for safety-critical applications

• 11.Fast Response Time:100-150 ms actuation speed for rapid actuator positioning in time-sensitive processes
