AFeatures
- They are easily adjusted in the field by removing the hex cap, making them ideal for pressure relief, liquid relief, bypass and over-protection.
- These units can be easily cleaned and maintained by simply removing the bonnet.
- Selected models have a bronze disc lapped into position to minimise leakage.
- They are available in brass, bronze and brass-bronze alloy body materials.
Working Mechanism
- Some pressure escapes through the water pipes that connect to the water heater.
- If it cannot, the pressure-relief valve is activated.
- The valve reduces the pressure to safe levels by releasing some of the hot water and air.
Standards and Approvals
- ISO 9001:2015
- CE
- CRN
- ASME
Frequently Asked Questions
How do you adjust a water pressure relief valve?
Many valves are equipped with a nut, screw or knob that allows you to adjust them. Turning the screw or knob clockwise raises the water pressure while turning it counter-clockwise lowers it.
Which series of valves are compatible for use with boilers?
Aquatrol 560/570 Series valves are high-capacity safety valves that are used for boilers, piping lines and vessel protection. They are intended for heavy-duty industrial applications.
Do these relief valves come calibrated?
Aquatrol 69 Series liquid relief valves are calibrated based on a range of flow rates (GPM) versus seat size and set pressure.
