Details about Temperature Pressure Relief Valve

Temperature Pressure Relief Valve


  • ASME-Code Fast-Acting Pressure-Relief Valves for Low-Pressure Steam
  • For Use With Steam
  • ASME Code IV for Low-Pressure Steam
  • Temperature: 110° F
  • These valves meet ASME Code Section IV for low-pressure steam-heating boilers requiring pressure relief at 15 psi.
  • All springs fully open at the set pressure and remain open until the system pressure is restored below the set pressure.
  • The body is bronze for durability and long service life.
  • Vented relief ports exhaust discharge directly.

Threaded relief ports can be attached to a drain line for remote discharge

  • The pressure-reducing valve adopts a piston structure, and the internal system is simple. The nut can be rotated through the movable joint, and only the sealing gasket can be placed to complete the installation.
  • This water pressure-reducing valve does not require a bypass pipe, and the distribution pipe is simple, saving a lot of space and distribution costs.
  • The water pressure relief valve has a pressure adjustment knob inside the top cover, adjusted freely. It is equipped with a pressure gauge for easy viewing of pressure.
  • The water pressure relief valve can withstand a pressure of 1.6 MPa and can be installed in front of most tap water equipment to regulate water pressure.
  • We strive to provide you with the highest quality product and customer experience. If you’re not entirely satisfied, please get in touch with us at any time.

If you’ve ever seen a movie where pipe bursts and floods the entire room, then you know how important it is to prevent pipes from bursting. A temperature-pressure relief valve is essential to any plumbing system that could help prevent this catastrophe. Here are some questions to ask yourself before deciding on a new one:

A) What type of piping do I use?

B) How many fixtures can my current valve handle?

C) Do I need a duplex or single-acting relief valve?

D) What should I do if my relief valve starts leaking?

E) Is there a way to test my current temperature-pressure relief valve?

You will see that most of the answers are related to your plumbing system and how it’s set up. This information is essential for you to decide when choosing a new one. Temperature Pressure Relief Valve Here are some questions to ask yourself before deciding on a new one: A) You first need to know what type of piping your home has, copper or PVC pipes. If you have copper pipe, it doesn’t require any particular parts when purchasing this kind of valve. Still, with plastic piping (PVC), you will need to buy a valve with the appropriate threaded fittings depending on the diameter and size of the piping. B) How many fixtures are attached to your relief valve? Most valves are rated at 150 PSI, but if you have more than one fixture, it’s best to upgrade to a higher-pressure-rated valve. C) Do you want a duplex or single-acting relief valve? A duplex is two independent valves in one body, while a single-acting valve only opens when pressure increases on one side. D) Another vital question is, what do I do if my relief valve leaks? If this happens, don’t panic! Shut off the water supply and call a professional plumber. E) Last, but not least, you should always test your current valve to see if it’s still working. One way of doing this is using a garden hose to mimic the increase in water pressure. Place the open end of the hose on top of the discharge pipe and turn on the faucet at full blast. If the valve opens, then it’s still functioning properly.

The radiator valve and thermostatic mixing valve are works for water temperature. All of these valves are work for water plumbing systems, plumbing repair, and installation. So have to let water shut-off and shut-on. Some heating systems are related to hot water and cold water mixing for temperature control and stability. Our intelligent valves are functional. There are applications in commercial, residential, and industrial areas.
