Constructed with a brass body, the Series 307 is designed for compatible water, air, fuel gas, compressor, carwash, filling machine, irrigation, packaging, thermoregulation, water treatment, plastic molding and industrial automation applications requiring dependable normally open 3 way operation and direct-acting control from 0 bar differential pressure. In its de-energised state, the valve operates in its normally open flow configuration and changes flow path when energised, subject to correct specification, media compatibility and installation. Dependable Normally Open 3 Way Control for Industrial Automation Ultravalve’s Midlands based warehouse offers a wide range of Series 307 valves from stock, subject to configuration and current availability. Designed to support maintenance projects, industrial automation upgrades, compressor systems, carwash equipment, packaging lines and water treatment requirements, these valves help provide fast replacement options for urgent pipework and general process applications. Normally Open Direct-Acting Performance: The 3 way normally open direct-acting poppet type design enables electrically actuated flow control and redirection from a minimum differential pressure of 0 bar. Defined Pressure & Flow: Supports a maximum allowable pressure of PS 50 bar, with maximum differential operating pressure dependent on orifice size, flow path and coil selection, reaching up to 12 bar on selected 1.2 mm configurations. Available with selected 1.2 mm and 1.5 mm orifice combinations, with Kv values from 0.04 to 0.06 m³/h. Brass Construction: Manufactured with a brass body and brass armature tube as standard, alongside an AISI 430FR plunger and core and AISI 302 springs. A stainless steel armature tube is available as an option. Seal & Fluid Compatibility: Seal materials are listed as NBR, FPM and EPDM, with suitability dependent on valve code, media, temperature and application compatibility. Maximum fluid viscosity is listed as 25 cSt. Steam Application Constraint: The maximum allowable pressure for steam applications is strictly limited to PS 2.5 bar gauge. Flexible Integration: Features a G1/8 ISO 228 threaded fluid connection for straightforward installation into compatible systems, with universal mounting position as stated in the product data sheet. An exhaust port with hosetail connection is available as an option. Continuous Electrical Duty & Protection: Uses compact Series 3 coils with continuous service ED100%. Electrical connection is DIN 46244 with PG9 connector, with protection rated IP65 when the connector is fitted and IP00 without connector. Additional Options & Temperature Guidance: Available with stainless steel armature tube, electroless nickel plating, Class H insulation, cable attached versions, special coil voltages, special coil powers and certified coils. A Series 7 explosion proof coil according to ATEX - EExmII is available subject to correct specification and application suitability. Ambient temperature is listed as -10°C to +80°C according to the coil.
