Descripción completa del producto

The Type SR, SRH, H High Capacity Safety Relief Valves are designed and constructed to meet the requirements of Section VIII ASME Boiler and Pressure Vessel Code and ANSI/ASHRAE 15 Code requirements and bear the ASME Code Symbol (UV). Safety Relief Valves should be used to protect each refrigeration system pressure vessel that can be isolated by valves. In many localities state or municipal codes govern selection and installation of Relief Valves. Employing proven principles of design, these Safety Relief Valves are highly reliable and dependable. Precision machined moving parts of stainless steel, and a PTFE disc prevent sticking due to corrosion or cold welding and assure valve opening at the set pressure long after installation. They are not suitable for corrosive ambient atmospheres such as chlorine, etc.

Markets:

• Industrial Refrigeration
• Commercial Refrigeration

Features and Benefits:

• ANSI/ASHRAE 15 Compliant
• Excellent Repeatability
• All Stainless Steel Internal Parts
• Unaffected by Vibration
• PTFE Seat
• Pressure Settings from 150 to 400 psi

Application:

• Compressor Packages
• Accumulator Vessels
• Receiver Vessels
• Anywhere overpressure protection is required
