The Armstrong Bellows Sealed Globe Valve features a double wall stainless steel bellows at the stem seal, and a graphite packing seal accessory to prevent leakage. The finely polished planar sealing between the valve and the seat ensures long-term, reliable, operation whether the stem is moving or not.
