High pressure needle valve

Characteristics

V8 series

Maximum working pressure: 689 bar (10000 PSI)

Operating Temperature

PTFE packing: -54 °C to 232 °C (-65 °F to 450 °F)

PEEK filler: -54 °C to 260 °C (-65 °F to 500 °F)

Graphite filler: -54 °C to 649 °C (-65 °F to 1200 °F)

Integrated valve body structure

Two section valve stem design, with special hardening treatment on the upper valve stem thread and rolling hardening treatment on the lower valve stem surface

The lubricating grease on the upper valve stem thread is isolated from the system medium

The non rotating lower valve stem moves up and down instead of rotating up and down, reducing the friction on the packing during each stroke and minimizing the bite between the valve seat and valve head

The valve has a back sealing function in the fully open position

Panel installation is possible

The handle is locked with screws at both ends, which is stable and durable

Multiple color handles available for selection

Each valve undergoes a sealing test with nitrogen gas at 6000 PSI before leaving the factory
