| Body Type | Typical Materials | Size Range (mm) | Pressure Rating | Temperature Range (°C) | End Connection | Typical Actuator Compatibility | Typical Applications | Test/Standards & Leakage | Manufacturing Notes |
|---|---|---|---|---|---|---|---|---|---|
| Wafer (short-body, resilient-seat) | Ductile iron, carbon steel, stainless steel; elastomer seats (EPDM/NBR) | 25–600 | PN6–PN16 / ANSI 150 | -20 to 120 (typical with EPDM); higher with alternative seats | Wafer (between flanges) | Manual gearbox, electric, pneumatic | Municipal water, HVAC, general low-pressure services | ISO 5208 / API 598 testing; soft-seat typically bubble-tight in normal conditions | Short face-to-face; cost-effective; sand-cast or ductile iron cast and machined |
| Lug-style (double-lug) | Ductile iron, stainless steel | 25–900 | PN10–PN16 / ANSI 150 | -20 to 150 (EPDM/optional PTFE) | Lug (bolt-through lugs enable single-side isolation) | Electric, pneumatic actuators; manual gearboxes | Fire protection systems, potable water, process isolation | ISO 5208; suitable for blind flange installations; soft-seat performance typical | Allows downstream maintenance without full line shutdown; lug machining required |
| Double-flanged (flanged both sides) | Carbon steel, stainless steel, low-alloy steels | 150–1200 | PN16–PN25 / ANSI 150–300 | -20 to 250 (PTFE/graphite seats possible) | Large electric, pneumatic, hydraulic actuators | Petrochemical, industrial process lines requiring bolted flanges | API 609 / ISO 5752 face-to-face compatible; ISO 5208 or API 598 testable | Heavier construction; precision flange surfacing and machining typical | |
| Butt-weld body | Stainless steel (304/316), duplex, alloy steels | 25–600 | PN16–PN40 / ANSI 150–300 | -50 to 400 (metal seats or high-temp packing) | High-temp electric/gearbox, hydraulic actuators | High-temperature steam, high-purity services, welded pipeline sections | Weld procedures per ASME/EN standards; API 598 testing available | Welded ends reduce leak paths; requires qualified welding and post-weld inspection | |
| Double-eccentric (double-offset) | Stainless steel, carbon steel, duplex | 50–1000 | PN10–PN25 / ANSI 150–300 | -29 to 350 (seat-dependent) | Electric, pneumatic, hydraulic actuators suitable for modulating use | Oil & gas, power generation, pulp & paper (modulating and isolation) | API 609 where applicable; ISO 5208; improved cycle life over concentric designs | Eccentric geometry reduces seat wear; precision machining required | |
| Triple-eccentric (triple-offset, metal-seated) | Stainless, duplex, alloy steels, specialized metal seats | 50–2000 | PN10–PN40 / ANSI 150–600 | -196 to 600 (depending on metallurgy and seat design) | Heavy-duty pneumatic/hydraulic/electric actuators | Critical isolation in refining, petrochemical, cryogenic and high-temp services | API 609 / ISO 5208 compatibility; metal-to-metal sealing engineered for near-zero leakage | High-precision CNC machining and finish grinding; higher manufacturing tolerance and QA |
