Why Haven’t Valves Changed in the Last 50 Years?
Well Now They Have … Introducing the Shutter Valve from Clarke Engineering!


July 2016, MARIETTA, GA ~

The Shutter Valve™ is an aerospace-inspired valve that revolutionizes flow control efficiency for customers that demand precise flow processing and a low total cost of ownership. The Shutter Valve is a bubble tight valve that provides a compact footprint, reduces water hammer, eliminates high frequency vibration and provides easy maintenance for greater uptime. Best of all, it’s the world’s first piggable control valve meaning you can clean your lines with the Shutter Valve in place. Now that’s innovation!

GOODBYE VALVE HEADACHES
The Shutter Valve is a quarter-turn, fully piggable valve that opens full bore and can be specified to sanitary Clean-in-Place capability. It is also designed to conform to the industrial standard ASME B16.34, ANSI, API, and AWWA certification standards. It is able to utilize any connection, such as NPT, Flanged, or Sanitary, to install the Shutter Valve without any alterations to your current system, and it works with either manual or automatic actuators.

INCREDIBLE PERFORMANCE
At full open, the Shutter Valve has 0% pressure drop (delta-P) and because there is nothing obstructing the flow path when open (like a disc of a butterfly valve) cavitation, water hammer, and overall wear-and-tear are lowered considerably. The flow characteristics are ideal for control valve applications due to the precision aperture control capability while the finely tuned petal designs limit cavitation to nearly undetectable levels.

BUBBLE TIGHT
The Shutter Valve has achieved the highest certification possible, Class 6 bubble tight shut off at 1,000 PSI meaning the Shutter Valve has zero leakage at operating pressure. This is the first time in history that the combination of precision flow control, zero pressure drop and bubble tight shut off has been combined into one valve.

DESIGNED FOR SAFETY
The low cavitation in the Shutter Valve produces very little noise when the valve is in partial open positions. Low noise provides a safety benefit for anyone who works in facilities as well as improving valve and pipe life through reduced high frequency vibratory modes.

ENGINEERED WITH PRECISION
Among the Shutter Valve’s several features, it boasts precision flow control. With its design based on a modified mechanical iris, the Shutter Valve enables you to control flow by moving the petals into any position needed. Flow can be restricted from a fine mist all the way to a full stream like a fire hose, and everything in between.

CFD (Computational Fluid Dynamics) analysis, using standard Navier-Stokes equations, has shown that the Shutter Valve eliminates the undesirable fluid disruptions of ball valves and butterfly valves. This means that the problems with noise, pumping losses, high energy costs and reliability will be greatly reduced with the Shutter Valve.

COMPACT DESIGN
The Shutter Valve has a simple operating mechanism that reduces the amount of space needed to install it. A trained technician can disassemble it for field maintenance or repairs in less than 15 minutes. This leads to greater uptime and efficiency. The standard face-to-face dimensions allows plug and play replacement of existing valves with little or no modification.

USE LESS ENERGY
Another advantage of the Shutter Valve is that because the petals open and close perpendicularly to the flow, instead of working against the flow, the amount of torque required to open and close the valve is extremely low. This means that the valve requires a smaller actuator to operate, thereby saving on power consumption. Using a smaller actuator significantly lowers the total package price.

VERSATILE
The Shutter Valve can be built from a variety of materials including, stainless steel, acrylic plastic, aluminum, cast iron, bronze, nickel or any other material, to suit each customer’s individual needs. All Shutter Valves are designed and manufactured in the US from the highest quality materials, to ensure reliability.

The Shutter Valve is ideally suited to industrial customers that require the unobstructed flow, piggability and sealing capability of a ball valve with the precise flow control of a control valve and compact size of the butterfly valve. Combined, these features provide one of the highest performing valves on the market today for virtually any application.
