A valve having a first valve body including a first contacting surface, a pressurized fluid supply path opening to the first contacting surface and a pressure-controlled chamber opening to the first contacting surface. Forged Steel Valves A second valve body includes a second contacting surface contacting with the first contacting surface and a valve path whose ends open to the second contact surface, and which connects fluidly the pressurized fluid supply path to the pressure-controlled chamber. A valve is arranged in the second valve body and moved to a closed or open position at which the valve means does or does not cut off the fluidal connection between the pressurized fluid supply path and the pressure-controlled chamber. An actuator arranged on the second valve body moves the valve to the closed or opened position. Balance ValvesA first drawing means presses the first contacting surface and the second contacting surface against each other. A second drawing means sets the actuator on the second valve body. The force of the first drawing means is not applied to the actuator and therefore the operation of the actuator is not disturbed by the force pressing the first contacting surface and the second contacting surface against each other. Also, the actuator can be removed from the valve without dissembling the first and second valve bodies.
