Bronze solenoid valves are suited for what we call a general purpose applications, such as air, water bronze solenoid valvessystems, vacuum, Argon, Helium, Oxygen, Nitrogen, light oils, and especially steam.
bronze solenoid valves are Bronze body, their internal parts typically being Bronze or various grades of stainless steel, i.e. 430F armature, AISI302 for springs, AISI304 for the core tube and any pressure support discs if used in conjunction with a sealing diaphragm.
Typically fitted with PTFE seals as standard for steam, sometimes with options for EPDM, NBR or FKM.
Zero rated bronze solenoid valves typically 0 to 10 Bar, Port sizes 3/8, 1/2, 3/4 and 1" thread.
Pilot operated Stainless Steel solenoid valves typically 0.2/0.5 up to 10 bar, Port sizes 1/2, 3/4, 1, 11/4, 11/2 and 2" thread or Flanged Dn10 to Dn50.
Bronze zero rated solenoid valves are designed to work with zero pressure differential i.e. with pressure zero rated bronze material valvedifference between inlet and outlet ports, suitable for most general purpose air, water, vacuum, steam applications and most non aggressive non corrosive liquid or gas media and especially good with low pressure gravity fed systems, closed loop systems or just simply where pressure differences are unstable or unknown. Sometimes referred to as assisted lift or hung piston solenoid valves the internal piston is attached or hung from the valve armature assembly to assist in the opening or closing of the valve.
Bronze pressure assisted solenoid valves are designed to work utilising the media system pressure bronze solenoid valvesdifferential i.e. the pressure difference between the inlet and outlet ports, suitable for many general purpose air, water, steam or light oil applications and most non aggressive non corrosive liquid or gas media and are especially good with higher pressure steam systems and open to atmosphere systems. Sometimes referred to as pilot operated valves or floating piston valves where the piston is not attached and simply floats according to the solenoid controlled pressure difference.
