Inteva — quick couplings from Spain since 1987.
Inteva is a family‑run Spanish manufacturer of quick release couplings, screw couplings, check valves and ball valves, built to international standards and exported to 67 countries. Cracking pressures can be specified to order.
What we stock from Inteva
Two lines, both about connecting and controlling flow.
Quick release couplings
Connect and disconnect a line without draining it — for attachments, test rigs and anything swapped often.
Inteva also make screw couplings, where vibration or a knock would part a push‑fit.
Quick release couplings →High pressure check valves
Designed to prevent the damage that fluid back pressure causes.
Opening and cracking pressures are available on request — so the valve can be matched to the circuit rather than the circuit worked around the valve.
High pressure check valves →Specify the cracking pressure
A check valve's cracking pressure is the differential at which it starts to open. Get it wrong and the valve either leaks by or never opens.
- Inteva offer various opening and cracking pressures on request, rather than a single fixed option.
- Tell us the circuit pressure, the flow, and what the valve is protecting.
- If you are replacing a valve, the old part number is usually enough.
This is the detail most often left off an enquiry, and the most common reason a check valve gets returned.
A medium-sized family business
Inteva is a family business with its own machinery park and engineering department, and it has invested steadily in staff training, technology, software and testing procedures.
The practical effect: it will engineer a variant for you where a larger manufacturer would send a catalogue.
