Abstract
The present invention is an improved clutch retention feature of a hand control valve. The hand control valve has a rotatable control member and a stationary member. There is a rotatable plate or disc which interlocks with the rotatable hand control member and a stationary plate or disc which interlocks with the stationary member. Adjacent surfaces of the stationary and rotatable plates are in sufficient frictional contact to maintain the hand control valve in the position set against system forces and yet be overcome by hand rotation of the rotatable control member.
