The Sierra Instruments 18-5819 and 18-5817 solenoids are engineered for reliable operation in mercury vapor recovery applications. These solenoids are designed to meet the specifications of Mercury Control Valve part numbers 89-818997A1.
The 18-5819 and 18-5817 solenoids feature a compact, rugged design with a powder-coated finish for durability in harsh environments. The solenoids are constructed with high-quality materials, including a brass body and stainless steel plunger, to ensure long-lasting performance.
The 18-5819 and 18-5817 solenoids operate on a 12V DC power supply and feature a quick-disconnect terminal block for easy wiring. The solenoids are designed to be operated in a wide temperature range, from -40 F to 158 F (-40 C to 70 C), making them suitable for use in a variety of industrial applications.
The 18-5819 and 18-5817 solenoids have a flow capacity of 0.14 gallons per minute (GPM) and a maximum operating pressure of 50 psi (3.45 bar). They are suitable for use with low-viscosity fluids and are designed to provide precise, repeatable solenoid valve action.
The 18-5819 and 18-5817 solenoids are backed by Sierra Instruments' commitment to quality and customer support. These solenoids are designed to meet the stringent requirements of mercury vapor recovery applications and are an excellent choice for those seeking reliable, high-performance solenoid valves.
The Mercury 18-5819, 18-5817, and Sierra 89-818997a1 are all solenoids used in various automotive applications. Here are some potential pros and cons of buying one of these solenoids:
Pros:1. Availability: These solenoids are widely available from various auto parts stores and online retailers.
2. Affordability: Compared to purchasing a new OEM solenoid from a dealership, aftermarket solenoids like these are generally more affordable.
3. Functionality: These solenoids are designed to perform the same function as the original equipment, which is to control the flow of fuel or other fluids in the engine.
Cons:1. Quality Concerns: Aftermarket solenoids may not always meet the same quality standards as OEM parts. Some users have reported issues with leakage or poor fitment.
2. Compatibility: It is essential to ensure that the aftermarket solenoid is compatible with your specific vehicle make and model. A poorly fitting solenoid can cause more harm than good.
3. Installation: Installing an aftermarket solenoid may require some mechanical knowledge and skills. If you are not confident in your ability to install it yourself, it may be worth considering paying a professional.
In conclusion, while aftermarket solenoids like the Mercury 18-5819, 18-5817, and Sierra 89-818997a1 can be an affordable alternative to OEM parts, it is crucial to consider their potential quality concerns and compatibility issues. If you are confident in your ability to install the solenoid and are comfortable with the potential risks, then an aftermarket solenoid may be a suitable option for you. However, if you prioritize quality and compatibility, it may be worth considering purchasing an OEM solenoid from a dealership. Ultimately, the decision is yours to make based on your budget, mechanical skills, and priorities.
