207

Series 207 Brass 2 Way Normally Open Servo-Assisted Solenoid Valve Ultravalve supplies the Series 207 2 way normally open servo-assisted diaphragm solenoid valve for automated on/off flow isolation in commercial and industrial systems. Constructed with a low lead brass body and cover, the Series 207 is designed for compatible industrial, water treatment, pneumatic, compressor, carwash, filling machine, irrigation, packaging, thermoregulation and general process applications requiring dependable normally open operation with a defined minimum differential pressure. In its standard de-energised state, the valve allows flow and closes when energised, subject to correct specification, media compatibility, pressure conditions and installation. Dependable Normally Open Servo-Assisted Control for Industrial Networks Ultravalve’s Midlands based warehouse offers a wide range of Series 207 valves from stock, subject to configuration and current availability. Designed to support urgent maintenance projects, industrial automation, water treatment, commercial carwashes and general pipework upgrades, these valves help provide fast replacement options for critical flow control requirements. Normally Open Servo-Assisted Operation: The 2 way normally open servo-assisted diaphragm design requires a minimum differential pressure of 0.15 bar to operate effectively, with selected reinforced diaphragm configurations requiring 0.5 bar. Defined Pressure & Flow: Supports a maximum allowable pressure of PS 25 bar, with maximum differential operating pressure dependent on connection size and orifice. Selected configurations reach up to 15 bar differential pressure. Orifice sizes range from 10 mm to 30 mm, with Kv values from 1.5 to 15 m³/h. Connection & Installation Guidance: Features ISO 228 threaded fluid connections from G1/4 to G1 1/4, depending on the selected version. The preferred mounting position is with the vertical coil above, as stated in the product data sheet. Low Lead Brass Construction: Manufactured with a brass / low lead brass NSF 61 body and cover, an AISI 303 armature tube, an AISI 430FR plunger and core, and AISI 302 springs. Seal Options & WRAS Approval: Seal materials are listed as NBR, FPM and EPDM, with EPDM certified WRAS available for compatible potable water applications where correctly specified. Maximum fluid viscosity is limited to 25 cSt. Electrical Duty & Protection: Uses Series 3 coils with Class F insulation, voltage tolerance of AC +15% / -10% and DC ±10%, and continuous service ED100%. Protection is IP65 with the connector fitted correctly and IP00 without connector, using DIN 46244 electrical connection with PG9 connector. Ambient temperature is listed from -10°C to +80°C according to the coil. Steam Application Constraint: The maximum allowable pressure for steam applications is strictly limited to PS 2.5 bar gauge. Configuration Options: Available options include electroless nickel plating, Series 7 explosion proof coil according to ATEX - EExmII, Class H insulation for Series 2, cable attached versions, special coil voltages, special coil powers and certified coils, subject to correct specification.
