H-680-SS-GL-1/4 Product Description

H-680-SS-GL-1/4 is a stainless steel instrument needle valve for precise liquid and gas flow regulation in industrial process pipelines. This instrument needle valve adopts 1/4 inch thread connection, stainless steel body with GL packing seal structure. The compact instrument needle valve supports manual rotary adjustment to control medium flow rate and realize shut-off function. This instrument needle valve serves flow control for sampling, pressure gauge and instrument isolation loops.

H-680-SS-GL-1/4 delivers reliable fine flow regulation for gradual adjustment of fluid flow in process measuring pipelines. Accurate fine flow regulation achieves tiny flow control through tapered needle stem structure. Stable fine flow regulation maintains consistent flow rate under pressure fluctuation. Dependable fine flow regulation supports medium sampling and pressure stabilization tasks.

This unit features GL packing sealing assembly for leak-proof performance under high working pressure. The robust GL packing sealing assembly reduces stem leakage during repeated rotary operation. The corrosion-resistant GL packing sealing assembly adapts to oil, water and weak corrosive gas. This durable GL packing sealing assembly simplifies on-site maintenance and packing replacement.

H-680-SS-GL-1/4 is widely used in petrochemical, power plant, water treatment and pressure instrument monitoring systems. It is equipped with handwheel for manual operation and easy opening/closing control. It has high pressure resistance and good anti-corrosion performance. It serves as common spare part replacement for process instrument pipeline control.
