I'm interested in sourcing a pressure reducing valve specifically designed for wet type fire hydrant applications. The valve should meet industry standards and be compatible with a fire fighting equipment setup. Please provide me with your specifications, pricing, and availability. Additionally, if you could share insights on the materials used and any certifications or compliance with safety regulations, that would be great. I'm looking for a reliable supplier who can ensure quality and timely delivery. Thank you!
