Product description
The 5″ (125 mm) DEMCO Series NE-D wafer butterfly valve is the short-neck wafer with body notches for the lightweight flange patterns used on tank trucks and bulk-handling equipment; it also self-centres in ASME Class 125/150 flanges. This page lists the 2 factory configurations we can supply in this size, each identified by its Cameron part number, with the body, disc, stem and seat it was built with. Every one is rated for 200 psi drop-tight, bi-directional shut-off in an ASME Class 150 body.
Configurations available
| Part number | Body | Disc | Stem | Seat |
|---|---|---|---|---|
J022184-1115311 | Ductile iron | Nickel-plated ductile iron | 416 stainless steel | Buna-N |
J022184-1115361 | Ductile iron | Nickel-plated ductile iron | 416 stainless steel | Natural rubber |
Trim is read from the part number using DEMCO's ordering table. Confirm against the nameplate when we quote.
Reading the part number
Take J022184-1115311. J022184 is the DEMCO base number for a 5″ Series NE-D valve at 200 psi. The suffix is read left to right: body configuration (1 = wafer), body material (1 = ductile iron), stem (1 = 416 stainless steel), disc (5 = nickel-plated ductile iron) and seat (31 = Buna-N). The last character is the operator code.
Performance
- Body rating: ASME Class 150 (285 psi non-shock).
- Shut-off: 200 psi drop-tight, identical from either flow direction.
- Vacuum: sealed against 10 microns (29.9 in Hg).
- Buna-N seat: 0°F to +180°F (−18°C to +82°C).
- Natural rubber seat: confirm the temperature limit for your fluid when we quote.
Construction
- Hard-backed cartridge seat: the elastomer is bonded to a rigid backing ring and can be replaced in the field without special tools.
- Triple stem seal and a dry stem journal keep line fluid out of the stem bore.
- Floating disc centres itself in the seat; the stem is blowout-proof.
- Double-D upper stem and DEMCO top flange accept the full DEMCO actuation range.
- MSS SP-25 marking on every valve.
Installation
The NE-D wafer body is notched for lightweight transport flange patterns and also self-centres between ASME Class 125/150 flanges on through-bolts. A wafer valve is clamped between two flanges and is not rated for end-of-line service.
Operators
The DEMCO top flange takes the 10-position locking handle, worm-gear operator and Series DR pneumatic actuators. Confirm the operator supplied with each part number when we quote.
