Angle Supply Valve CALEFFI 338 (MPN 338452) for Heating Systems

CALEFFI angle supply valve model 338 is a compact angled feed and shut-off valve designed for heating and hydronic systems. The valve provides reliable flow control and isolation at an angled pipe connection, making it suitable for installations where space is limited or an offset connection is required. It is intended for use in residential and light commercial boilers, radiators, and manifolds as part of circulation and distribution circuits.

Advantages

The valve features a compact angled body that simplifies installation in tight spaces and reduces the need for additional fittings. Its shut-off function allows for maintenance and component replacement without draining entire circuits. Constructed for compatibility with common heating system piping, the valve ensures straightforward connection and stable flow regulation when used in routine heating applications.

Suitable for

• Residential boiler supply and return connections
• Radiator feed and isolation
• Manifold branch isolation in hydronic circuits
• Light commercial heating installations with angled pipe runs

Key specifications

• Valve type: angled feed and shut-off valve
• Application: heating and hydronic systems
• Body design: compact angled configuration for limited space installations
• Functionality: flow control and circuit isolation
• Compatibility: suitable for typical residential and light commercial piping materials and fittings

How to use

Install the valve at the point where an angled feed or shut-off is required, ensuring proper alignment with the pipework and compatible fittings. Use appropriate sealing materials and torque values recommended for the piping system to secure connections. Operate the valve handle to open or close flow as needed for commissioning, balancing, or isolating sections of the heating circuit. Verify leak-tightness after installation and during system start-up.

Usage recommendations

For reliable operation, select a valve size and connection type that match the system piping and operating pressure. Periodic inspection for leaks and accessible operation of the shut-off mechanism is recommended, and any servicing should be performed with the circuit isolated and cooled according to standard safety procedures.
