Frequently Asked Questions

What is a forged steel check valve and how does it work?
A small-bore piston or disc check valve whose body is forged rather than cast. Forward flow lifts the piston off its seat; reverse flow and gravity drop it back. Forging removes the porosity a casting can carry and aligns the grain structure, so the same wall holds far more pressure — which is why forged bodies are used almost exclusively for small-bore high-pressure check duty.
Which body, disc and seat materials are available?
Body and bonnet in ASTM A105 carbon steel, ASTM F304L or F316L stainless, or F11, F22 and F91 alloy steels for elevated temperature. Disc or piston in forged carbon steel or stainless variants (F304L/F316L). Sealing seat is a metal-to-metal forged seal as standard, with optional PTFE or soft-seated inserts where a tighter shut-off on clean service is needed.
What size and pressure class apply?
15 mm to 50 mm (½″–2″) in Class 800# to 1500#. This is deliberately a small-bore, high-pressure valve — for larger lines at lower class use the wafer or swing check designs. MVS is ISO 9001:2015 certified and supplies test certificates with every order.
When should I specify a forged rather than a cast check valve?
Whenever the line is 2″ or smaller and the class is 800 or above — a cast body would need considerably more metal to reach the same rating, and small castings are harder to keep free of porosity at high pressure. Forged valves also suit alloy steel service (F11, F22, F91) for steam and high temperature. Above 2″, forging becomes uneconomic and a cast body is the right answer.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS manufactures at its own works — since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. Alloy steel bodies, soft-seated inserts and specific end connections are built to order.
