Subplates, also known as mounting pads, are designed to connect a hydraulic valve to field piping. Much like a switchboard on a circuit, subplates let you control how much fluid flows between components in hydraulic machinery. How do subplates work?Subplates can have up to seven valves mounted in parallel connection. They’re used for any type of valve mounting, such as direction-control valves or pressure-relief valves.How to choose the right subplatesWhen choosing the right subplates there are a number of factors to take into consideration. Material and finish will determine how much pressure a subplate can handle, and will inform the durability of the unit. Most subplates are made from galvanised steel to prevent rust, which is vital when working in moist conditions. Other considerations include thread size and connection port thread – both of which are variable depending on the intended application. Subplates are available in modular or single-station formats to suit requirements and the number of modifications needed.
