Thermostatic valve Afriso ATV 336 DN25 Rp1 kvs 9 60°C (S)

The Afriso ATV 336 thermostatic valve DN25 Rp1 kvs 9 60°C (S) is a temperature-controlled valve designed for maintaining or limiting fluid temperature in heating and hot-water systems. Built for stable automatic regulation, the valve responds to sensor or actuator inputs to control flow and keep the downstream temperature at or below the set point of 60°C. The product is suitable for installations where reliable temperature control and safety limiting are required, such as radiator connections, mixing circuits and safety return lines.

Advantages

The valve offers a compact DN25 body with Rp1 threaded connection and a kvs 9 flow characteristic that enables predictable hydraulic behaviour across common heating system conditions. Its temperature-limiting setting at 60°C provides a clear control point for systems that require a fixed maximum temperature. Designed for compatibility with standard sensors and actuators, the valve supports automatic operation without continuous manual adjustment and helps reduce the risk of overheating or scalding in supply lines.

Suitable for

• Radiator connections requiring temperature limitation and automatic control
• Mixing circuits for blending supply and return flows to achieve stable temperatures
• Hot-water systems where a fixed maximum temperature of 60°C is needed for safety
• Temperature safety return lines and boiler protection applications

Key specifications

• Nominal size: DN25
• Connection type: Rp1 (internal thread)
• Flow coefficient (kvs): 9 m³/h
• Set temperature: 60°C
• Control type: thermostatic, temperature-actuated
• Typical installation: inline valve for heating and hot-water circuits

How to use

Install the valve in the supply or return line according to pipeline flow direction markings and applicable installation standards. Connect a compatible sensor or actuator to the thermostatic element, ensuring correct placement for accurate temperature measurement. Once mounted and connected, the valve will modulate flow automatically to maintain the set temperature of 60°C; verify tightness of threaded connections and bleed air from the system before commissioning. Periodic inspection for leaks and proper actuator response is recommended to ensure continued performance.

Usage recommendations

Use the Afriso ATV 336 in systems with fluids and pressure ratings compatible with DN25 valves and Rp1 connections. Ensure the sensor or actuator used is suitable for the valve’s thermostatic element and for the system’s temperature range. For reliable operation, follow local plumbing and heating codes during installation and schedule routine checks to confirm the valve operates within the intended temperature limits.
