They are available in a basic 90 degree swivel configuration, fitted with an air set pressure control/ deadman valve or fitted with an electrically controlled pressure control/deadman valve which is suitable for use with Digital Pressure Control systems. Connection options are either 4” BSPP or NPT female thread and a trolley option can be provided. For lower flow rate applications a 3 inch pressure control module is available.
