Why New York mechanical contractors choose ValveAtlas HVAC butterfly
Wafer vs Lug selection expertise. Wafer (BWN) between flanges for in-line service; Lug (BLN) with threaded bolt holes for dead-end and maintainable service.
EPDM (water) or NBR (oil) seat material. Spec seat to fluid — EPDM for glycol and chilled water, NBR for hydraulic and compressor oil.
Double-eccentric for bubble-tight. BLN-0401 has offset pivot for zero-leakage class A shutoff on steam and high-pressure water mains.
Approved-equal submittals
Where a specification names a specific manufacturer, we prepare an approved-equal submittal package (dimensional drawings and material data) for review by the engineer of record and the authority having jurisdiction.
