20140326338 | ROTARY STEM POSITION INDICATOR - 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. | 11-06-2014 |
20140291561 | MAGNETIC ROTARY ACTUATOR - 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. | 10-02-2014 |
20140102575 | ENERGIZED PACKING RETAINER - Disclosed herein is a dual packing retainer and dual sealing ball valve for use generally in high pressure applications. Further disclosed herein are methods of detecting seal failure before the ball valve must be taken offline due to the presence of secondary or backup seals. | 04-17-2014 |
20140097371 | PIGGING BALL VALVE - Improved ball valve or pig valves with stems having higher stress yields are disclosed. Additionally, a method of changing using the same stem in a ball valve or pig valve in a low pressure application or a high pressure application is disclosed. Furthermore, a method of ensuring a correct stem is matched to a correct ball of a ball or pig valve is disclosed. | 04-10-2014 |
20140097365 | ROTATABLE ACTUATOR SHAFT - Disclosed herein are apparatuses and methods of preventing rotational stress on the top shaft of valve actuators. Certain methods and apparatuses include a bifurcated top shaft. Other apparatuses and methods include a method of preventing rotational stress at the distal end on the top shaft of an actuator. | 04-10-2014 |
20140097364 | ADJUSTABLE DIAPHRAGM RETAINER PLATE - Disclosed herein are improved diaphragm actuators capable of preventing the inhibition of movement of a diaphragm retainer plate when a stretched or improperly sized diaphragm is used. Such diaphragm retainer plates may be adjustable such that the thickness from the distal side to the proximal side is increased. Methods of preventing such inhibition of movement are also disclosed. | 04-10-2014 |
20140097363 | FLOATING SEAL RETAINER - Configurations of piston actuators having seal retainers doubly acting as pressure chambers are disclosed. Further disclosed are methods of installing pressure chambers in piston actuators. | 04-10-2014 |
20140096676 | CYLINDRICAL LINER FOR PISTON ACTUATOR - Disclosed herein are new types of hydraulic piston valve actuators wherein the piston is replaceable with different sized pistons. Further disclosed are parts of the piston interchange system resulting in the fewest number of parts changed between one piston diameter and another piston diameter. Methods of changing from one piston diameter to another piston diameter are also disclosed. | 04-10-2014 |
20140069512 | AUTOMATIC BARREL PIG LAUNCHER - Disclosed herein is an automatic barrel pig launcher with an actuated ball valve and a rotating magazine that contains one or more pigs. The automatic barrel pig launcher comprises a plate bore, bottom plate bore, upper case bore, and throughbore of a ball that, when aligned, provide loading of the pig into the throughbore of the ball. The pig is launched by opening the ball valve. Also disclosed herein are systems and methods of use of the automatic barrel pig launcher. | 03-13-2014 |
20130313451 | DIAPHRAGM ACTUATOR - A valve actuator apparatus having improved diaphragm retention to protect against tensile loading and ability to adjust the top shaft diameter within said actuator. | 11-28-2013 |
20130312840 | VALVE ACTUATOR SYSTEM - A valve actuator apparatus and method for preventing latitudinal movement of a diaphragm actuator spring. The downstop is fitted with spring retainers to prevent latitudinal movement of the spring upon compression. | 11-28-2013 |
20130248001 | LOW PROFILE HYDRAULIC ACTUATOR - Hydraulic valve apparatuses with a low profile and without a top shaft are disclosed. Additionally, hydraulic valve apparatuses with indicator markers and side windows are disclosed. | 09-26-2013 |
20130234055 | DUAL PISTON PNEUMATIC ACTUATOR - 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. | 09-12-2013 |
20130233389 | HYDRAULIC ACTUATORS - 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. | 09-12-2013 |
20130214188 | ADJUSTABLE STROKE ACTUATORS - 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. | 08-22-2013 |
