Gate Valves
Wedge Gate Valves
Vastas Wedge Gate Valves are API 600 licensed. They are preferred as closure (shut-down) valves. Upon request it can be manufactured in bigger sizes and from various materials. Custom-made wedge gate valves are manufactured to meet the requirements for high-pressure water, sea water and waster-water systems. SIL 2&3 certified When required it can be manufactured from special material according to NACE corrosion standards and/or temperature class.

Conduit Gate Valves
Vastas Conduit Type Valves are API 6D licensed. They are suitable as line valves. Like Ball Valves they have DBB, FB, ASD, FSD, SLS, ESL features. They are suitable for pig transmission too. They can be used both for above ground and under ground applications.
It can be used as an isolating valve in pig loading-unloading platforms, in pump or compressor & in RMS stations, storage and distribution terminals.
SIL 2 & 3 certified. When required it can be manufactured from special material according to NACE corrosion standards and/or temperature class.
Through Conduit Slab Gate Valve - E50B
Through Conduit Slab Gate Valve - E50B
This type is designed and produced for pipelines. It should be preferred for On-Off services. Emergency Shutdown, Line Break and Remote Control types provide sound operation of the line. They are manufactured with a full bore section equals to pipeline cross section. Opening without decreasing the differential pressure is not recommended.
These Gate Valves are designed as pipeline valves and have piggable feature. Disc is designed as one-piece slab and the rings are floating type.
