69 Series Bronze Adjustable Relief Valve

Aquatrol 69 Series relief valves (field-adjustable) are used for controlling or limiting the system pressure to protect pumps, tanks, hydraulic equipment and pipelines. These units feature a bronze body with excellent ductility and corrosion resistance and manual adjustment of the relief pressure set-point by changing the force exerted by the stainless-steel spring. They come equipped with a hex cap for shielding the complete assembly and dual-lapped metal seating for eliminating leakages. Choose from an extensive range of these safety relief valves available in factory set pressures ranging between 15 & 300 psi on Raptor Supplies.

Features

  • 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.
