In the world of valve applications, asking the right questions is critical to determining which valve is the best fit for your application. The applications Versa valves are used in range from medical equipment to off-road vehicles to offshore platforms. All of these applications have one important thing in common – when called on to work, they must operate without fail. Product selection in these applications has a tremendous impact on cost, productivity, and safety.

Many solenoid valve installations for process valve automation are in environments that require some kind of solenoid and body exhaust protection. Most installations use a form of sintered metal muffler or filter, however these options tend to clog and become less efficient at protecting the valve. Any restrictions in exhaust flow have potential to affect the ability of the valve to switch position.

Actuator solenoids are certified by multiple standards and notified bodies worldwide, including ATEX, CSA®, FM™, IECEx, Inmetro (Brazil), KC (Korea), PESO (India), TR-CU (Russia), TS (Taiwan), and UL® in order to ensure worker and public safety, for example, when dealing with hazardous materials, environments or emergency shut down situations. These organizations are legislatively empowered in particular countries or regional jurisdictions to define product performance standards that must be met or exceeded in order to be legally certified for use in most applications.
Latching valves are particularly suited to applications where it is desirable or mandatory to manually reset or restart a system.
A typical application could involve the emergency shutdown of automatically monitored process operations. Loss or interruption of the control signal to the valve actuator causes the valve to shift, latch, and shut-down a process step. When the signal is restored the valve remains in the latched position until the operator manually unlatches it and allows the process step to resume. Positive latching in such an application is vitally important since many process operations are sequential and one step must not be started until the one ahead of it has started.

Versa’s single stage, high-pressure regulator is the ideal first cut Natural Gas high-pressure regulator. It is designed to accept up to 6000 psi input and reduce it to a working range of 10 to 500 psi. The Type ARH-316 Series of stainless steel regulators are designed to stand up to the harshest environments while providing highly accurate pressure regulation. Proven 316L stainless steel housing assembly and stainless steel diaphragm make the ARH-316 ideal for challenging applications such as pipelines, offshore platforms, and sour gas media.
If ever there is a time when a system absolutely cannot fail, it’s your emergency shut down safety system during an event. These systems are critical to minimizing the impact of potentially disastrous situations such as fire, process irregularities, or storms.
The solenoid valve, frequently taken for granted as a commodity, is actually an essential component in the Emergency Shut Down system. How the solenoids function can mean the difference between a successful emergency shut down or failure. Failure can result in loss of life, an environmental catastrophe, and/or significant financial loss for your organization.
Versa's AFH-316 Series of stainless steel filters are designed to stand up to the harshest environments while providing system protection from contamination. Proven 316L stainless steel housing assembly with two types of filter elements, polyethylene or 316L stainless steel, make the AFH-316 ideal for challenging applications such as pipelines, offshore platforms and sour gas media.
