    9140 Naphtha Dump Valve

The Y&F 9140 Series Naphtha Dump Valves are used for naphtha and water purge applications for aeroderivative turbines. This two-position, two-way, pilot operated design will fail closed upon loss of electrical power. The valve is a spring closed, energize to open design. A three-way, two-position pilot valve is used to operate the valve. Flow from the valve inlet to the outlet controlled by a poppet. A spring, along with pressure forces, holds the poppet in the closed position. The pilot valve, when energized, directs flow from the valve inlet to a piston attached to the poppet. This causes the poppet to be pushed against a stop, opening the valve. A minimum differential pressure of 30 psid is required for the valve to open when it is energized.
