Angled ball valve for boilers ARCO VA30 1/2" male BSP x 1/2" female BSP with butterfly handle

The ARCO VA30 angled ball valve for boilers with 1/2" male BSP to 1/2" female BSP connection and butterfly handle is designed for hot water and heating systems. Its compact angled body allows installation in confined spaces on boiler outlets and return lines. The valve provides quick on/off control and reliable shutoff to isolate sections of piping for maintenance or emergency service while minimizing flow resistance.

Advantages

The angled design saves space and simplifies alignment with boiler ports. The butterfly (wing) handle offers fast manual operation without tools and clear visual indication of open or closed position. Constructed for compatibility with common heating system fluids, the valve ensures tight sealing and reduced risk of leakage when properly fitted. Its construction supports routine maintenance and replacement of downstream components.

Suitable for

• Residential and small commercial boiler outlet and return lines
• Hot water circulation and heating circuits
• Isolation of radiators, pumps or sections of piping for service
• Retrofit installations where space is limited

Key specifications

• Connection: 1/2" male BSP (GZ) to 1/2" female BSP (RN)
• Mounting orientation: angled (elbow) body for compact installations
• Actuation: manual butterfly (wing) handle for on/off control
• Medium: hot water and heating fluids
• Function: quarter-turn ball valve for rapid shutoff

How to use

Install the valve on the boiler outlet or return line using compatible 1/2" BSP fittings and ensure thread sealing is applied according to system practice. Position the valve so the butterfly handle is accessible for manual operation. Rotate the handle 90° to move between open and closed positions; the handle alignment indicates flow state. Before installation or service, depressurize the system and drain if necessary to avoid scalding or leaks.

Usage recommendations

Verify compatibility with your heating system materials and operating temperature. Use appropriate thread sealant or tape on BSP threads and tighten fittings to recommended torque levels. Periodically operate the valve through a full cycle to prevent seizing in infrequently used circuits and inspect for signs of wear or leakage as part of routine system maintenance.
