Product Description
Bellows Globe Valve - Engineered for superior sealing performance in demanding industrial applications requiring zero stem leakage and reliable operation.
Product Overview
Bellows globe valves utilize bellows as the primary stem sealing element, specifically designed for applications with stringent stem sealing requirements. These valves are ideal for high-vacuum environments and nuclear industries where preventing stem leakage is critical for safety and operational integrity.
The bellows expand and contract with stem movement, eliminating traditional packing gland leakage while maintaining system integrity. Maximum working pressure is determined by bellows pressure resistance and fatigue strength characteristics.
