Coffee with Caleffi: Controlling Plumbing Pressure with Direct Acting Pressure Reducing Valves
A properly selected, installed and maintained pressure reducing valve (PRV) keeps your plumbing system in good working order. Kevin Freidt, director of product management, will walk you through each of these "insurance policies" to help you avoid pitfalls along the way.
You'll learn:
- What is a "direct-acting" PRV and how does it work?
- Where is a direct-acting PRV used?
- What happens if a PRV is undersized? Oversized?
- What are the most common causes of "failed" PRVs?
- Is it OK to install two PRVs in series if I have high supply pressure?
- Is it OK to install two PRVs in parallel if I have high flow requirements?
- Do I need to install a domestic hot water expansion tank in a system with a PRV? What will happen to the PRV if I don't have an expansion tank?
- What does it mean if my PRV is making noise?
- Does a PRV require maintenance?
Kevin is the intellect behind sizing up the best products to offer in a moving target market and manages an exceptional technical support team.Our audience will thoroughly appreciate his academic passion and concise content delivery cultivated from 30+ years’ of experience in the commercial HVAC industry.
