Product detail

Axial on-off valve

Product Code: Axial on-off valve

Describe: This valve is specifically suitable for severe duty on-off (upstream) and for quick-acting safety applications (HIPPS). Pressure has no impact on the operating forces, and the valve can be opened against full differential pressure.

Type designation

Safety shutdown valve or isolating valve

Typical applications

Severe-duty on-off (upstream)
Quick-acting on-off (HIPPS)
Flow line and header on-off
Critical isolation, start-up and blow-down
Switching valve (mol sieve)

Special features

Custom-designed
Safety: secured process isolation by means of reliable on-off technology (HIPPS)
Very fast stroke times : 20” Class 1500 in less than 2 seconds.
Suitable for infrequent use: operating forces do not increase over time. No-sticking.
Full range of matching Mokveld pneumatic and hydraulic actuators with tailored control arrangements is available. Electric and electro-hydraulic actuation is also available.
