When it comes to overpressure protection, in unique situations, end users have long been forced to choose pressure relief valve (PRV) orifice sizes that are too large for the application. This approach often leads to unnecessary system modifications, increased maintenance, and higher long-term costs, all to properly accommodate an oversized PRV. At Flow Safe, we recognized this gap for small orifice PRV’s and set out to engineer a solution that delivers both operational efficiency and long-term value: the F84-1A pressure relief valve.
The Problem with Oversized and Undersized PRVs
Selecting a pressure relief valve that doesn’t quite fit the application is more than a minor inconvenience—it’s a decision that can have ripple effects throughout the life of your system. Oversized PRVs, for example, are prone to valve chatter, premature wear, and frequent maintenance, while undersized options may not provide adequate protection. Both scenarios often force operators into costly tubing modifications or additional valving, undermining the goal of efficient, reliable overpressure protection.
A Smarter Solution: The F84-1A
The F84-1A was developed to address this exact challenge. By introducing an intermediate orifice size between our existing -1 and -2 options, we’re giving operators a tailored solution that fits their system’s needs—no more, no less. This not only reduces the risk of valve chatter and extends valve life but also eliminates the need for expensive system modifications that can erode the value of your initial investment.
Why Life-Cycle Value Matters
The F84-1A represents a move towards smarter, more sustainable decision-making. Its zero-leakage plastic seat, tested to ASME Section XIII and API 527 standards, prevents media loss and optimizes system performance over time. Precision-machined components and robust construction ensure that the F84-1A stands up to the most demanding environments, reducing the frequency and cost of repairs.
Key Features at a Glance
- ASME Section XIII Compliance: “UV” stamped and certified for gas/vapor service, ensuring regulatory peace of mind.
- National Board Capacity-Certified: The F84-1A is certified under NB-18 (certification no. 28066), ensuring reliable performance.
- Adjustable Blowdown: Fine-tune reseating characteristics between 5-20% for optimal system control.
- Material Versatility: Available in a range of metallic and soft good materials to suit your specific application.
