DN15 (1/2") Flanged Actreg Actuated Ball Valve | PN40 | Spring Return (Fail Safe Closed) | 230VAC | VIZ 001 Switchbox
The BV-L6N00P40DN0015AC031SR is a DN15 (1/2") flanged actuated ball valve assembly rated to PN40 pressure, combining a 2-piece full-bore stainless steel ball valve with an Actreg spring-return pneumatic actuator, a 230VAC solenoid valve (SCG551A001MS), screw-type manual override, and a VIZ 001 IP68-rated limit switch box. The spring-return actuator provides fail-safe closed operation — the valve closes automatically on loss of air supply or electrical power, making this assembly ideal for safety-critical shut-off applications. Flanged DIN connections make this assembly suitable for flanged pipework systems where screwed BSP connections are not appropriate.
Key Features
- Spring Return Actuator – Air Open / Fail Safe Closed – The valve opens when air is applied to the actuator via the solenoid and springs closed automatically when air or power is lost. Essential for safety shut-off and emergency isolation applications.
- PN40 Pressure Rating – Higher pressure rating than standard PN16 valves. Suitable for pressurised water systems, steam-adjacent pipework, and high-pressure industrial processes.
- Flanged (DIN) End Connections – Flanged connections suit pipework systems where welded or flanged joints are preferred. Compatible with DIN-standard pipe flanges.
- 230VAC Solenoid Valve (SCG551A001MS) – Operates from standard 230V AC mains voltage, allowing direct integration with UK industrial control panels. Compatible with PLC relay outputs rated for 230VAC.
- VIZ 001 Limit Switch Box (IP68) – Provides visual position indication plus two microswitch outputs (250V, 10A, 2 x M20 cable gland entries) for PLC/SCADA position feedback. IP68 rated for wet or outdoor environments.
- Screw-Type Manual Override – Enables manual operation of the actuator without air supply for commissioning, testing, or emergency use.
- Stainless Steel A351 CF8M Body – Grade 316 equivalent stainless steel provides corrosion resistance for a wide range of industrial media.
- PTFE 1600 Seat – Chemically resistant, low-friction seat for reliable sealing and long service life.

Typical Applications
This flanged, fail-safe closed actuated valve assembly is well-suited to emergency shut-off systems, building management systems (BMS), water treatment, chemical processing, pressurised HVAC circuits, and industrial applications where mains voltage (230VAC) electrical control with fail-safe closed behaviour is required in flanged pipework.
