A lock up valve works by sensing the drop in pressure at the signal port. Once this pressure is lower than the adjusted spring compression, the valve closes the control ports, isolating the downstream circuit. The Sitecna LK pneumatic lock up valve range combines extreme sensitivity to changing pressure, single or dual circuit operation and comprehensive certification to deliver optimum performance in harsh conditions. Precision manufactured from 316L stainless steel or copper free aluminium, the LK lock up valve range is ideal for use in valve actuation systems and pneumatic automation where pressure control and redundancy are crucial.
For environments where explosion risk is important, the LK range carries ATEX and GOST Ex certification as standard.
LK has NPT threads as standard in 1/4″ sizes for outlet pressures up to 7bar. The maximum inlet pressure is 10bar for the stainless steel and aluminium constructions. Sensitivity as low as 0.1bar for the setpoint. LK08 is the 1/2"NPT variant.
There is a choice for elastomers to suit different ambient temperature ranges down to -55degC making it suitable for installations in all industrial situations.
Sitecna manufacture all their products in Italy to strict quality controls with full material traceability.
