Parker's PB11/12 is a stainless steel particulate filter/regulator that provides accurate pressure regulation and high moisture removal efficiency in a compact package. PB11/12 is a one piece combined filter/regulator which minimizes space and piping by incorporating two units into one. A large diaphragm to valve ratio provides precise regulation and good flow capacity.
The PB11/12 comes standard with stainless steel bowl, adjustment springs, body, bonnet, bottom plug and poppet for applications in corrosive or wash down applications. For specific flow and space restricted applications, this product can provide a solution that does not sacrifice performance. The various options available such as auto drain, low temperature seals, pressure range and panel mounting capabilities make this series easy to configure for your application.
