Gate Valve is a genuinely new equipment_category — it appeared only as a family name in the general catalog with no matrix cell. Distinctive construction worth publishing: a sliding cylindrical (tapered) plug design giving a larger seating area than a conventional gate valve, no metal-to-media contact anywhere, non-rising stem, body-bottom clean-out/drain plug, full vacuum service rating, positive bubble-tight shut-off, sealed visual position indicator. The three size-dependent pressure tiers are the real quoting trap: a 12" Type P is rated to half the pressure of a 4".

Real Specifications
| Type P Gate Valve pressure by size | 150 psi @ 70°F (1-1/2"-8"); 110 psi (10"); 75 psi (12"-14") — three distinct pressure tiers | asahi-america-metal-replacement-valves.md |
| Type P Gate Valve construction | High Impact PVC body, sliding cylindrical (tapered) plug design, no metal-to-media contact, full vacuum service rated | asahi-america-metal-replacement-valves.md |
| Series 19 MAV pairing | Series 19 MAV MultiPack (1/2"-4") pairs with diaphragm AND gate valves — the only Series 19 sub-model rated for multi-turn valves | asahi-america.md |
The three size-dependent pressure tiers are the real quoting trap on this valve: a 12" Type P is rated to half the pressure of a 4" — using the smaller size's 150 psi rating against a 12" line is a real oversight risk.
Gate valves are multi-turn, so the quarter-turn CAV/SAV actuators in Asahi's own lineup don't fit — MAV is the only Series 19 sub-model rated for multi-turn service, which is a real compatibility check that has to happen before an automated gate valve quote goes out, not after.

FAQ
Is Gate Valve used in Chemical Processing?
Gate Valve is a genuinely new equipment_category — it appeared only as a family name in the general catalog with no matrix cell. Distinctive construction worth publishing: a sliding cylindrical (tapered) plug design giving a larger seating area than a conventional gate valve, no metal-to-media contact anywhere, non-rising stem, body-bottom clean-out/drain plug, full vacuum service rating, positive bubble-tight shut-off, sealed visual position indicator. The three size-dependent pressure tiers are the real quoting trap: a 12" Type P is rated to half the pressure of a 4". This is strong evidence.
