Features; Specifications - Yoshitake GP-1200 Installation And Operation Manual

1. Features

GP-1000 Series pressure reducing valves for steam are pilot-operated valves which can be used with
confidence for small to large flow rate, in a host of applications ranging from building utilities systems,
air-conditioning systems, and factory systems, etc.GP-1200 and 1210 models can be used as pneumatic,
remote type valves, making them well suited for systems where the pressure setting is frequently
changed, or for centralized control system.
