Abstract: A manual gate valve operator used in the oil and gas industry. The operator does not allow an increase or decrease in height when manually rotating the hand wheel. Instead, the operator has an internal indicator nut of the position of the valve. The indicator nut is observable electronically or visually.
Abstract: Disclosed herein is an improved automated impactor turn wheel capable of being activated and used to turn valves from a remote location. In certain instances, the impactor turn wheel is contemplated to turn a ball valve. The improved impactor turn wheel will generate increased torque which will allow improved operation of a ball valve in high pressure applications.

Abstract: Hydraulic valve apparatuses employing the use of multiple pistons for opening and closing gate valves are disclosed. Additionally, hydraulic valve apparatuses with a low profile and without a top shaft are disclosed.
Abstract: Dual piston pneumatic actuators used in opening and closing gate valves are disclosed. The actuators allow for pressure to vary based on opening or closing a gate valve versus keeping the gate valve open or closed.
Abstract: A valve actuator apparatus and method for adjusting for valve bore drift using an adjustable downstop is disclosed. The adjustable downstop comprises a downstop and a drift adjuster. The drift adjuster can me moved in an upwards or downwards direction to increase or decrease the stroke length of the operator shaft.
