Description
The Parker PB548 / PB558 comes standard with stainless steel bowl, adjustment springs, body, bonnet, bottom plug and poppet for applications in corrosive or wash down applications. It is a stainless steel particulate filter/regulator that provides accurate pressure regulation and high moisture removal efficiency in a compact package. PB548 / PB558 is a one piece combined filter/regulator which minimises space and piping by incorporating two units into one. A large diaphragm to valve ratio provides precise regulation and good flow capacity.
The various options available such as auto drain, low temperature seals, pressure range and panel mounting capabilities make this series easy to configure in a wide range.
