摘要:
A pilot valve that includes a pilot valve body including a chamber, a first fluid inlet and a second fluid inlet for providing fluid to the chamber, and a fluid outlet for receiving fluid from the chamber. The pilot valve further includes a separating element and a valve rod, the valve rod is arranged to control fluid flow from the first or second fluid inlet to the fluid outlet via the chamber. The separating element is connected to, and movable with the valve rod, and has a first fluid contacting area configured to be in fluid communication with the first fluid inlet, and a second fluid contacting area configured to be in fluid communication with the second fluid inlet and arranged on an opposite side to the first fluid contacting area. The pilot valve is at least partly controlled by a difference between a first force and a second forces acting on the first and second fluid contacting areas of the separating element.
