The valve assembly has a second fluid circuit valve assembly which includes a second fluid circuit valve adjustor configured to actuate an adjustor shaft and an adjustor circuit coupled with the adjustor shaft. An input to the second fluid circuit valve adjustor translates into a movement of the adjustor shaft. The adjustor circuit also includes a second fluid circuit valve and a secondary first fluid circuit valve which is located in a first fluid circuit flow path of a first fluid circuit valve. The secondary first fluid circuit valve adjusts flow through the first fluid circuit flow path when the second fluid circuit valve adjustor is in a closed position. ## Claims ### Claim 1 A valve assembly configured to control a first fluid circuit and a second fluid circuit, said valve assembly comprising: a second fluid circuit valve adjustor configured to actuate an adjustor shaft;
