- European Product.
- All SAVAL valves are subjected to rigorous tightness and
mechanical resistance tests of the housing and the seat. - Materials sourced only from approved foundries, using the best
materials depending on the application. - Saval valves are stronger and more durable because the body and bonnet are
reinforced. - Disc (single piece) with stop nut for optimal sealing.
- The (metal-to-metal) seat union is not damaged when the plug closes on the ring.
(of the seat) - Higher pressure without loss due to the characteristics of the valve stem.
- Possibility of mechanical opening indicators

Packing change
Saval's design allows replacement of the packing without the need to isolate the valve and avoid shutting down a production line or pressure in a piping system.
See the following instructions for replacing the packing:
-
1
Open the valve fully so that the valve is in the upper position.
-
2
Loosen the bolts on the sides of the cable gland and remove it.
-
3
Remove the gasket using the appropriate tool.
-
4
Prepare new packing material by cutting this mitre.
-
5
Fit successive turns of packing ensuring that the cuts are positioned at 90° on the successive turns.
-
6
Replace the cable gland.
