Stainless Steel 316 Freeze Protection Valve for Emergency Showers & Eye Wash Systems – Thermostatic, Automatic Drain at 1–4°C, Corrosion-Resistant

Category: Brand:

Description

Application
This 316 stainless steel thermostatic freeze protection valve automatically opens to drain or establish flow when the temperature drops below 4°C, preventing ice formation and freeze damage in critical safety systems. It modulates closed as temperatures rise, ensuring efficient, self-regulating operation without external power.
Ideal for emergency showers, eyewash stations, fire protection lines, condensate systems, pumps, and other freeze-sensitive equipment—especially in outdoor, unheated, or cold-climate installations. Also serves as reliable backup protection for traced (heat-traced) piping systems.
Design Features

* Stainless body and thermal element
* Narrow temperature band
* Compact, low mass – Fast response
* Ram-type plug for reliable tight shut off
* Sensitive to temperature only
* Unaffected by pressure variations
* Easy installation with pipe wrench
* Discharges the minimum amount of water required to prevent freeze damage

Operation

A thermostatic element inside the valve senses temperature and if this falls below 35°F (1.7°C) the valve modulates open allowing water to flow. The valve will remain open as long as the water flowing by the sensor is less than 40°F (4.4 C). However, when the water flowing by the sensor becomes greater than 40°F (4.4°C) , the valve will close.
