Bürkert00456534Servo-Assisted 2/2-Way Diaphragm Solenoid Valve – NPT 3/8, 10 mm Orifice, Brass, EPDM, 24 V DC

Product Description

What this part is: Bürkert 00456534, a Type 6213 A servo-assisted 2/2-way diaphragm solenoid valve for liquids. Series: Type 6213 EV. Circuit Function: A — 2/2-way, normally closed, inlet at port 1. Orifice: 10 mm (3/8 in). Port Size: NPT 3/8. Port Type: Internal thread. Body Material: Brass. Diaphragm Material: EPDM. Operating Pressure: 0 – 10 bar (0 – 145 psi). Coil Voltage: 24 V DC. Coil Power: 10 W. Country of Origin: Germany. How the servo-assisted design works: A servo-assisted valve uses line pressure, not solenoid force, to lift the main diaphragm, so a 10 W coil switches a 10 mm bore against 10 bar — a duty that would need a far larger direct-acting solenoid and a far larger coil. On the Type 6213 the diaphragm is spring-coupled to the armature, and that spring link pulls the diaphragm open mechanically at the start of the stroke, so the valve opens from zero differential pressure upward rather than needing a minimum head across it. The body is also damped for low switching noise. Pressure and flow data: Operating Pressure Range: 0 – 10 bar (0 – 145 psi). Orifice: 10 mm. Nominal Diameter: DN 10. Port Size: NPT 3/8, internal thread both ends. The 10 mm orifice on a 3/8 in port keeps the bore at full port size, so the valve is not the restriction in a 3/8 in line. Materials: Body Material: Brass. Diaphragm Material: EPDM. EPDM suits water, hot water, low-pressure steam, glycol and dilute aqueous chemistry, and it is the standard Bürkert choice on potable and process water duty. Brass gives the pressure rating and the thread strength at a lower cost than the stainless-steel body option in the same family. Electrical connection: Coil Voltage: 24 V DC. Coil Power: 10 W. Electrical Connection: Form A cable plug to DIN EN 175301-803. That is the industry-standard 18 mm form-A pattern, so the coil takes a Bürkert Type 2508, 2509 or 2518 cable plug, or any equivalent form-A plug, and a Type 1087 timer plug fits the same spade pattern for cyclic duty. 24 V DC drive lets the valve be switched directly from a PLC output card or a relay contact on control-voltage wiring. Quantity and configuration: Unit Quantity: 1 Pc. Supplied as a complete valve: brass body, spring-coupled EPDM diaphragm assembly, armature and stopper set, and the 24 V DC solenoid coil.
