Press Release Summary:
Able to be used in existing unloader system or on its own as optimized alternative to traditional finger style and plug style unloaders, ZVI unloader valve can be serviced in field without additional machining. This piston-style unloader can be used in all brands of compressors, at any speed, for both lubricated and non-lubricated cylinders. Also, solution supports use with virtually any gas where max DP across unloader is up to 1,500 psi.
Original Press Release:
New ZVI Unloader Valve from Zahroof Valves Replaces Traditional Plug and Finger Models
New design can be used in an existing unloader system or on its own
HOUSTON -- Zahroof Valves Inc. (ZVI), established with a focus on improving the performance of reciprocating compressors through the introduction of its game changing compressor valve and industry-leading 10 year warranty, today announced the launch of its newest product: the ZVI unloader valve.
The ZVI unloader valve is a patent-pending piston-style unloader, designed to greatly improve reliability over traditional finger style unloaders, and features a much lower added clearance volume compared to plug style unloaders.
Setting the ZVI unloader valves apart is the ability to service them in the field without any additional machining. It is a more reliable unloader as there are no fingers acting against a dynamic valve element. Unlike a plug-type unloader, there is not a large increase in clearance volume in the cylinder that can detrimentally affect the compressor throughout. The flow through the unloader is better than in the case of plate or channel valves, improving unloaded power as well as eliminating drag forces and aerodynamic flutter of valve elements. The new unloaders do not have the misalignment / assembly issues of plug style unloaders. The actuation force required for the ZVI unloader valve is much less than that required for a plate, channel or plug style unloader.
It is possible to replace multiple existing unloader systems at a corner of a cylinder with a single ZVI Unloader system, utilizing regular suction valves in the other locations.
The ZVI unloader valve can be used in all brands of compressors, at any speed, for both lubricated and non-lubricated cylinders. It can be used with virtually any gas where the maximum differential pressure across the unloader is up to1500psi.
"The ZVI unloader valve is an important advancement in a compressor industry where breakthroughs are few and far between," says Zahroof Mohamed, President of Zahroof Valves. "The flexibility in the design makes this technology applicable to users who are planning on an upgrade to an existing unloader system, adding a complete unloader system to a unit or to the OEM compressor manufacturer who is looking for a reliable cylinder unloading system.
"The design of the unloader system for a specific application is backed by analysis and simulation using ZVI's Dynamic Compressor Simulation program. In an economy where it is important to reduce operational costs, the ZVI unloader does so by reducing down time, reducing maintenance costs and improving efficiency."
ZVI's flagship product, the StraightFlo Valve (SFV), is a patent-pending, revolutionary, reciprocating compressor valve technology that results in step improvements in valve performance through its unique design. The innovative design, based on the patented Modular Reed Valve technology, delivers a step change in reciprocating compressor performance, serviceability and reliability while reducing gas emissions to the environment.
