Description
Female-thread stainless steel check valves protect pumps, gauges and process branches from backflow on NPT, G or metric ports. FerruleX machines SS304, SS316 and SS316L bodies for 1/8–1 inch and M10–M24 threads. Across maker series, stainless instrument check valves are commonly rated 3000–6000 psig CWP depending on size and series, with cracking pressure set per spring option. Use this style when both sides of the line are already threaded and a compression ferrule would only add joints. Arrow direction is part of the order — state it on the RFQ with thread standard, spring option and quantity. Stocked threads ship from the factory without a cart checkout. Do not use a check valve as the only isolation point; add a ball valve upstream if the element must come out. Values are class-typical references for this configuration; threads, cracking pressure and pressure class are confirmed on the RFQ.
Thread sealant belongs on the male mating part, not inside the female check-valve bore, or it can foul the poppet. Confirm whether the line needs a soft seat or a metal seat before FerruleX releases the lot. Cracking pressure is quoted, not assumed from the catalog pressure rating.
- Ends
- Female NPT, G, ZG(R) or metric.
- Sizes
- 1/8"–1" and M10–M24.
- Role
- Reverse-flow protection on threaded manifolds.
