Efficient strangulation with minimal stretching or erosion of the disc or seat.
Short stroke of the disc and few turns to actuate them, which reduces the time and wear on the stem and bonnet.
Precise traffic control.
Available with multiple drills.
Through conduit gate valves are used in applications like: offshore platforms, onshore terminals, transmission lines.Commonly used types of medium in these applications are: non-corrosive liquids, gas, water, sour service, hydrocarbon liquids or gas
Through Conduit gate valves can be used in many applications.
They allow the fluid to flow in a fully open position and be restricted in the fully closed position, with minimal load losses. Not recommended for intermediate positions.Gate valves are bidirectional and can be installed horizontally or vertically.
Service with opening or total closing, without strangulation
For rare use
For minimum resistance to circulation
For minimal amounts of fluid or liquid trapped in the pipe
1. Straight-through stop valve. The stem of the straight-through stop valve forms a 90° angle with the center line of the medium passage. This type of stop valve is the most widely used in power plants. Direct current globe valve. The direct-flow globe valve is an angle between the valve stem and the center line of the medium passage. 2. The straight-through type refers to the horizontal straight-through type, which corresponds to the angle type. The direct current type is generally a kind of straight-through valve, and the direct current generally flows directly without a curved flow path in the middle. The straight-through type can have S-shaped flow passages, such as most of the globe valves and regulating valves
Sizes: 2" - 42" Classes: 150 - 1500 SCV Valve manufactures some of the most dependable cast steel Thru Conduit Slab and Expanding Gate Valves in the industry. Both designs utilize flanged and butt-weld end connections, and are manufactured and tested in accordance with API 6D.
Through Conduit Gate valves offer increased value by incorporating advanced design features. These valves are designs and manufactured with a full bore port, rising stem, OS & Y type with floating seats. These valves are robust in construction and easy In-Line maintainability.
