Angle control valve with manual knob SCHLOSSER 15 mm model 601400022

SCHLOSSER angle control valve with manual knob, 15 mm connection size (model 601400022) is an angled regulating valve intended for manual flow control in heating and plumbing installations. The valve provides a compact solution for adjusting the flow of water or other compatible heating media in domestic and commercial systems. Its 15 mm connection size fits standard small-diameter copper, plastic or multi-layer pipework commonly used in radiator, towel rail and distribution circuits.

Advantages

The valve features a manual knob for direct, stepless adjustment of flow, enabling precise balancing and zone control without the need for tools or actuators. Its angled body saves installation space and simplifies connection to radiators or wall-mounted manifolds. Constructed for reliability in typical heating system conditions, the valve offers consistent operation and straightforward maintenance access.

Suitable for

• Manual flow adjustment on radiators and towel warmers
• Balancing small heating zones in residential and light-commercial systems
• Connection to 15 mm copper, PEX or multilayer pipes
• Replacement of existing angled valves with 15 mm fittings

Key specifications

• Connection size: 15 mm
• Valve type: angled control valve with manual knob
• Operation: manual, stepless adjustment
• Application: heating and plumbing systems for regulating flow
• Mounting orientation: angled (90° connection between inlet and outlet)

How to use

Install the valve in-line with the system pipework, ensuring correct orientation of the angled body towards the radiator or manifold. Use appropriate fittings and sealing methods for 15 mm copper, PEX or multilayer pipes, and tighten to recommended torque values to avoid leaks. Rotate the manual knob to increase or decrease flow; adjust gradually while monitoring system temperature or flow indicators until the desired balance is achieved. Where the valve replaces an older unit, drain the circuit and follow standard safety procedures before removal and installation.

Usage recommendations

For reliable operation, use the valve only within the temperature and pressure ranges specified by the heating system manufacturer. Periodic inspection for leaks and smooth operation of the knob is advised; if stiffness or leakage occurs, isolate and service the valve according to local regulations. When integrating into hydronic systems, balance the circuit by incremental adjustments and measure performance to achieve efficient heat distribution.
