Angle Mushroom Valve ARCO Z0915, connection 1/2" x 3/4" (Regula)

ARCO Z0915 is an angle mushroom (sleeve) valve engineered for plumbing systems that require a compact shut-off solution with mixed connection sizes 1/2" x 3/4". The right-angle body allows inline isolation of water supply lines for radiators, domestic heating circuits and service points, enabling maintenance or component replacement without draining the entire system. Its compact footprint and straightforward operation make it suitable for installations where space is limited.

Advantages

The valve offers a durable shut-off mechanism in a compact right-angle form factor, reducing the space needed for installation. It is compatible with common plumbing fittings thanks to its mixed connection sizes and provides reliable isolation for maintenance tasks. The simple sleeve (mushroom) design ensures intuitive operation and effective sealing when closed, while the robust construction is intended for long-term use in residential heating and service applications.

Suitable for

• Radiator supply and return lines
• Domestic heating circuits and zones
• Service points and maintenance isolation
• Installations with limited space behind panels or furniture

Key specifications

• Connection sizes: 1/2" x 3/4" (mixed inlet/outlet dimensions)
• Angle body: right-angle configuration to save installation space
• Operation type: mushroom (sleeve) shut-off mechanism
• Intended media: cold and hot water for heating and service applications
• Typical use: inline isolation for maintenance and repair

How to use

Install the valve in the pipeline at the point requiring isolation, ensuring the correct orientation for the 1/2" and 3/4" connections. Tighten fittings to recommended torque for a leak-free joint using appropriate sealing materials or glands as per installation practice. Operate the mushroom sleeve by turning or actuating the control to close or open the water flow; verify sealing after closing and check for leaks after opening. Use standard plumbing tools and follow local codes and safety practices during installation.

Usage recommendations

For reliable performance, install the valve in accessible positions to allow periodic inspection. Before long-term commissioning, flush the system to remove debris that can affect the sleeve seal. If used in heating systems, bleed trapped air from radiators after installation and verify compatibility with system temperatures and pressures.
