These safety valves are ideal for the protection of equipment working with non-hazardous air, gas or steam, but which are handled at pressures that can cause occupational accidents. Their technical characteristics are:
- They are made of brass/bronze.
- Handles pressures from 3 to 300 PSIG.
- They have a grooved piston disc.
- It is capable of working from -51°C to 219°C without problems.
- They have an o-ring that prevents leakage and improves operational performance.
- They have dual control rings that offer easy adjustment for precise opening and accurate purge control.
- They have a pivot between the disc and the spring that corrects misalignment and compensates for the side thrust of the spring.
- They comply with ASME standards section I and VIII, steam, ‘V’ and ‘UV’; section VIII, air/gas, ‘UV’; and PED for non-hazardous gas.
The Kunkle relief valve model 6252 is made of cast iron, has a closed spring and a stainless steel trim for longer life and improved performance.
They can be used for steam boilers, steam generators, air and gas compressors, fluid pressure reducing stations, tanks, oil and gas separators, etc.
The most important technical characteristics of this pressure elief valve are as follows:
- It has an internal half-nozzle.
- They have lapped seats for flat optics.
- They offer a heavy-duty lifting lever assembly.
- Bolted hood design for easy maintenance.
- They comply with ASME standards section I, VIII and XIII and PED/PE(S)R13.
- They have dual control rings that offer easy adjustment and facilitate precise opening and accurate purge control.
They are valves that work with air, gas, steam, liquid with the highest efficiency in the industry.
The Kunkle 900 series valve models are the 910, 911, 916, 916, 917, 920, 921 and 927. All of these models are manufactured with high strength materials, depending on the type of customer application.
They have elastic seats that prevent fluid leakage and ensure greater efficiency and control in operations.
The Kunkle valve 920, for example, has a stainless steel body and hood design, with a threaded cap and a high-strength spring that make it ideal for industrial applications involving the vaporization of organic fluids.
Other features include:
- They feature stainless steel springs for temperatures up to 288 °C (550 °F) and an optional alloy spring that withstands up to 427 °C (800 °F).
- They have threaded caps and threaded side outlets.
- The pivot disc on Kunkle 900 series valves have pivot discs that perfectly align the seat and improve workability.
- They comply with ASME Section VIII, ‘UV’; Section I, ‘V’, with National Board approval and PED certification for non-hazardous gas applications.
This is a kunkel valve used to handle gases, vapors and air in boiler and generator applications or any industry where low pressures need to be controlled with maximum efficiency.
They come in sizes from 1 ½” to 6″ and can operate up to 250 PSIG with temperatures up to 406°F.
Its characteristics are:
- Lapped seats.
- Heavy duty lifting levers.
- High quality cast iron construction.
- Bolted hood design for easy maintenance.
- Double control rings provide easy adjustment for valve opening.
- They comply with ASME standards section I, VIII and IV, steam, ‘V’ and ‘UV’; section IV, steam, ‘HV’, with National Board approval and PED certification for non-hazardous gas applications.
We are Kunkle valves distributors and we have models 230/330/330S/333S, which are control devices used for high pressure air and gas services without fire.
The general characteristics of these relief valves for air are as follows:
- They feature a lightweight aluminum construction that is resistant to external and internal environmental corrosion.
- They have a repeatably consistent opening pressure and smooth relieving action.
- They offer positive resettlement with minimal pressure drop.
- They feature a soft o-ring seat that provides repeatable leak-tight performance. This is a great benefit because it reduces maintenance costs and provides multiple cycles with tight shut-off and high sealing integrity.
- Models 330, 330S and 333S incorporate a differential mechanism that maintains a predetermined seat contact load.
- They comply with ASME standards section VIII, XIII and I, gas ‘UV’; section IV, vapor ‘HV’, with National Board approval and PED certification for non-hazardous gas applications.
