Daniel 700 series control valves are self-contained and externally pilot-operated, so one basic valve can perform many different functions such as on-off control, pressure reducing, rate of flow control, back pressure or pressure relief, and differential control.

Daniel models 762, 763, 765, 766 and 767 gas loaded relief/back pressure control valves are specifically designed to regulate and control maximum pipeline pressures or to maintain a minimum back pressure in a system.

Daniel model 702 and 702A shock free check valves are designed to prevent reverse flow with a smooth shock-free closure.

Daniel models 531, 532, 578, and 588 power cylinder control valve is designed for applications where it is not practical to use the flowing stream as the power medium to operate a valve. These valves are suited for applications such as tank safety, remote on-off control, bypass control on distribution systems, emergency shut-off on loading and unloading lines, and two stage or digital batch control.

Daniel 600 series aircraft fueling control valves are specifically designed for fueling trucks, hydrants and service carts used in the fueling of jet aircraft.
