Grenton Thermoelectric Solenoid Actuator Normally Closed M30 230 VAC Black

Thermoelectric solenoid actuator for precise flow control in heating and cooling systems, featuring a normally closed design that ensures fail-safe operation by shutting off flow when de-energized. The M30 x 1.5 mm thread delivers universal compatibility with standard valve bodies and manifolds, while the 230 VAC supply integrates seamlessly into building automation networks.

Advantages

Silent thermoelectric operation eliminates water hammer and mechanical wear, extending service life. The 100 N closing force guarantees a tight seal against pressure differentials, and the IP54 rating protects against dust and splashing water. With a compact black housing and 1-meter cable, installation is straightforward in confined spaces.
