Parker Expands Offering for Pneumatic Lockout Valves with New Compact LV Series, High Flow LV Series, EZ Series and LVSS Series


RICHLAND, Mich.--une 28, 2013; Parker Hannifin Corporation, the global leader in motion and control technologies, has expanded its Standard LV Series Pneumatic Lockout Valve with new Compact and High Flow versions, extending the application range of the series with additional body and port sizes. The lockouts are installed in pneumatic drop legs or individual pneumatic control lines. In compliance with OSHA Standard 29 CFR Part 1010, the lockout valves are used during the maintenance of pneumatically operated equipment. The valves help protect maintenance personnel from being harmed by a machine that might otherwise engage while they are working on it.

The Standard LV Series features port sizes ranging from 3/8 inch to 1-1/4 inch and is ideal for most applications. The new Compact version, which features 1/4 inch and 3/8-inch port sizes, is for smaller machines such as packaging and machine tools where space is at a premium, but must still meet OSHA requirements. The High Flow LV Series, which features 1-1/2 inch and 2-inch port sizes, is ideal for higher flow applications such as power generation and pulp and paper. All versions operate in temperatures ranging from 40 degrees F to 175 degrees F (4.4 degrees C to 79.4 degrees C). The Compact version handles inlet pressures of 15 to 145 psi, while both the Standard and the High Flow versions handle inlet pressures of 15 to 300 psi. All versions are inline or surface mountable and come in safety yellow and red for high visibility.

Additionally, Parker is introducing the EZ Series of Pneumatic Lockout Valves, which meet all of the same standards as the LV Series, with the added feature of a soft start when opened. The handle pushes to close and pulls to open, but when pulled open, an adjustable needle valve controls the rate of pressure build-up. This can protect equipment during start up after maintenance. The valves feature port sizes ranging from 3/8 inch to 1-1/4 inch and handle inlet pressures of 30 to 150 psi.

Also, Parker's new LVSS Series comprises corrosion-resistant stainless steel versions of the LV Series, providing the only OSHA approved option in the industry for lockouts made from stainless steel. The valves are suitable for washdown areas in food, beverage, chemical, pharmaceutical, and oil and gas industries as well as outdoor environments.

The LV, EZ and LVSS Series all improve on the common, non-OSHA approved approach of using a traditional ball valve to shut off the air to a machine during maintenance. Unlike traditional ball valves, the Parker solutions are dedicated energy isolation devices. As such, they are easily identifiable, only lockable in the OFF position and have a full exhaust port.

Additionally, an important new option for the LV, EZ and LVSS Series valves is a visual indicator that verifies energy isolation by popping-up when the valve is open and air is flowing. This is the only solution available in the industry with a built-in visual indicator.
