Clarke Valve Passes External Leakage Requirements of API 607 Fire Test – March 13, 2020
Clarke Valve, a Chevron Technology Ventures portfolio company, is excited to announce that the reliable, low-torque #ShutterValve has passed the external leakage requirements of the API 607 fire…
Amazing Technology
The Shutter Valve™ derives its design from aerospace industry techniques for fluid control, sealing and mechanical systems. Clarke valves have countless millions of hours in service, starting with several years of testing in various real-world environments and conditions, resulting in a perfect valve for customers that demand precise flow processing and a low total cost of ownership. Engineered to be bubble tight, compact, precise, low-torque, inexpensive and ultra-high quality for easy maintenance and greater uptime. Proudly made in the U.S.A.
Universal Mating
With identical End-to-End Dimensions of ASME B16.10 Globe and Ball Valves, no modifications are required for installation. Works with either manual or automatic ISO 5211 actuators.
Inherent Geometric Benefits
Continuous center operation provides virtually no noise or cavitation levels. Curved petals allow smooth, predictable pressure drops, while center notches protect the seals and provide a tight shut off.
Yes, Even Class VI
Optional Class VI “bubble tight” shut off up to ASME Pressure Class 1500 means zero leakage at your operating pressure, with precise throttling capability that's easily programmed into your PLC.
Designed For Safety
ASME B16.34 tested & inspected at 1.5 X specified operating pressure before leaving our facility.
Precision Rangeability
Our aperture creates a centralized flow stream anywhere between a fine mist to a wide-open port, resulting in certified 500:1 Rangeability, 10X better than Globe Valves.
Incredibly Compact Design
On a Cv equivalent basis, we're 20% the size of other valves, with 20% of the weight, while maintaining the ideal equal percentage valve characteristic. Made possible by our unique geometric mechanical design.
Energy Efficient
Our petals open and close perpendicular to the flow, thus reducing the required torque of our valve. That means you can go electric where you couldn’t before, and valve automation costs are significantly reduced.
Versatile
Available in Bronze, Carbon Steel, Stainless Steel, and other custom materials, to suit your individual needs.
The design of the Shutter Valve allows for substantial savings in raw materials and dramatically reduces automation requirements. This means you can expect to spend anywhere from 50% to 80% less than the cost of equivalent Globe Valves. Many of our customers and partners already do, and continue to come back for more. Without any loss in performance, quality, maintainability or any other key features, the Shutter Valve simply improves on legacy valve types. We’re the LED light of the valve industry.
Most of the fugitive emissions from refineries are due to valve stem leakage, from Globe Valves and other legacy valve designs. The Shutter Valve earned its API 641 and ISO 15848 certification, along with the trust and investment capital of the world’s largest oil and gas producers, by allowing only 20 PPMv methane leakage. By contrast, a typical “low emissions” Globe Valve releases 500 PPMv. Limit wasted resources, prevent pollution, and avoid costly fines, with the Shutter Valve! We’re the catalytic converter of the valve industry.
Whether you are sizing valves for a Navy submarine, an oil refinery, an offshore facility, or a chemical plant, space always comes at a premium. With the incredibly compact Shutter Valve, and its very small automation footprint, the more of our valves you have installed, the more space you free up for other critical components and operators. We’re the transistor radio of the valve industry.
Clarke Valve meets or exceeds ANSI B16.34 wall thickness requirements throughout our product line for each appropriate pressure class. Yet, our valves weigh only 1/5th as much as competing Globe Valves! This is due to the Clarke Shutter Valve’s unique geometric configuration, while using all the same materials and manufacturing processes as other valve types. We’re the jet engine of the valve industry.
