Stainless ball valves NAVAL

Stainless ball valves designed for NAVAL use as shut-off valves for installation in pipelines various technological processes: acid-base tubes, the compressed air systems, pipes for raw and oxygenated water and different sites require high antikoroziynogo.

Basic parameters: DN 10 - 300;
PN 40,25,16;
T to +200C;
Connection: welded, threaded, flanged.
The types of the ball valves Naval:
1. Crane welded DN 10-250, PN 40,25,16.
2. Crane welded with gear DN 125-250, PN 16
3. The valve flanged DN 15 to 250, PN 40,16
4. Flanged valve with gear DN 125-250, PN 16
5. Valve with internal thread DN 10 to 50, PN 40
6. Crane welded/ with internal thread DN 10 to 50, PN 40

Bulk - stainless ball valves are designed for use in as shut-off valves. Cranes are manufactured for operation at pressure PN from 16 to 40 and sizes from DN 10 - 100. They can be used for installation in pipelines of various technological processes: acid-base pipes, compressed air systems, pipes for raw and the oxygen-containing water and at various sites where you want increased anticorrosives.

SPECIFICATION MATERIALS

POS NAME MATERIALS
1. Housing Carbon steel St 37.8
2. The spindle sleeve Carbon steel Fe 52 DP
3. Ball Stainless steel AISI 304
4. Spindle in Stainless steel AISI 303
5. Seal Polymer

11. The limiter Stainless steel AISI 304
12. Handle Galvanized steel

DESIGN:
The body and fittings are welded into a single unit. Carbon-Teflon gaskets, reinforced L-shaped rings. Resistant to to wear, chemicals and pollution. Thanks and polished polished balls, made of stainless steel faucet easy to use and works reliably, and after many years of operation.
Belleville springs press seal to the floating Orb. So by the way, the crane has a high density at low and high extremes pressure. Protivoyadii spindle is sealed by two O-shaped rings, of which the upper replaceable (in the modify DN 65-100 both replaceable).
Teflon gasket between the spindle and the spindle sleeve works as a sealing surface.

PROPERTIES:
The valve requires no maintenance, it is not necessary to tighten or grease. Long life, fast installation and low maintenance.

High spindle with round external shape of the crane do insulation work easy. The handle is removable and can be moved 180 degrees. The construction doesn't have heavy and weak casting parts. The drive mechanism is easy to install even after installation of the crane.
