Speciality Valves
Custom-engineered valves and strainers for applications that fall outside our standard product lines — damper gears, large basket strainers, float-type check valves, and other purpose-built solutions. Made to order, designed around your spec.
Purpose-Built Valves for Non-Standard Applications
Not every flow-control problem fits a standard product. UNP’s Speciality Valves range covers the purpose-built equipment our customers ask for again and again: pneumatically-actuated damper gears for ducting, oversized basket-type strainers, and float-actuated check valves for vertical and horizontal pump-protection service.
Each speciality product is engineered around your application requirements — size, media, pressure, mounting orientation, actuation method, and accessory specification. We work directly with EPC contractors, OEMs, and plant engineers to build what the standard catalogue can’t supply.
If your application needs a custom valve solution that nobody else seems to make, this is where the conversation starts.
