H1700 Heavy Duty Ball ValveThe H-1700 Series is a high performance instrumentation ball valve for general service. The H-1700 series fits heavy duty service, thanks to its superior robust design, featuring ease of use and high cycle durability.

H-1700 series validation included thermal-cyclic tests in 200°C, -40°C and room temperature at maximum allowed working pressure (6000 psi). It features large and agronomic handle for better grip while working in the field and more suitable for heavy duty service and operation.

The valve is built with two locking nuts on the stem, allowing for longer service life and high levels of safety. Similar valves from other manufactures are usually built with only one nut.
