Product Details:

Watts 530C-STD adjustable relief valve is designed to control or release built-up pressure in the system, which may otherwise damage pipelines and equipment. This pressure relief valve is used in fire protection systems.

Working Mechanism:

  • Watts 530C-STD adjustable relief valve features a calibrated adjustment mechanism to set the valve to the acceptable relief pressure.
  • When the set steam internal pressure is encountered in systems containing air, oil or water, the unit opens and rises due to spring action.
  • This ultimately helps fluid escape till the pressure of the steam inside the boiler is dropped to the required levels.

Features:

  • Watts 530C-STD adjustable relief valve opens at a preset pressure value and discharges fluid until the pressure drops to acceptable levels.
  • This pressure relief valve has brass body construction for enhanced durability.
  • It comes with 1/2 inch NPT threaded male inlet and threaded female (drain) outlet connections for rigid sealing and optimum functionality.
  • The stainless steel spring protects the system or vessel from high pressure.
  • This adjustable relief valve comes equipped with a brass bonnet, Buna-N disc and Buna-N O-ring to ensure a prolonged life.
  • The calibrated adjustment characteristic is engineered for setting the valve to the required relief pressure and is ideal for bypass thermal expansion pressure relief.
  • Watts 530C-STD adjustable relief valve delivers a maximum pressure of 150 psi.

Compatible Accessories:

  • Watts O-rings: These round rubber washers create a watertight seal and prevent leaks in valve systems. They are designed for Watts 530C adjustable relief valves.

Standards and Approvals:

  • FDA
  • NSF

Frequently Asked Questions:

Q. Where should a pressure relief valve be installed?

A. Pressure relief valves should be installed near the tank on the cold water line.

Q. Who founded Watts?

A. Joseph Watts founded the company 'Watts Water Technology' in 1874 with the hope that water boilers in textile industries should not explode.

Q. Can a pressure relief valve be installed upside down?

A. A pressure relief valve can be mounted upside down, however, the best way to install a pressure relief valve is in a vertical position, which means the spindle should be vertical and the valve should be in an upright position.

Q. What is the difference between a flow regulator and a pressure regulator?

A. Flow control valves are used for controlling and adjusting fluid or gas flow through a system. On the other hand, pressure control valves are used to regulate the pressure of a fluid passing through a pipe.
