The VTDM Combination Block system includes a thermostatic valve, a minimum pressure valve, supports for spin-on separators, oil filters and relative nipples, as well as extra ports to monitor pressure in the separator tank and connections to the intake valve and scavenge line. Combination blocks can be threaded or flanged on a separator tank or assembled separately. Some VTDM are also available in ‘upside-down’ version (with oil and air filters at the bottom position). Thermostatic units are available at different working temperatures. The oil and separator nipples are available with  different sizes upon request. Filters can be supplied separately on demand. The VTDM Combination Block are also available for Natural Gas and Water Lubricated applications.
