Slab Gate Valve -> API Slab Gate Valve Slab gate valves are usually used for the oil & gas pipe-lines. Double block and bleed capability and automatic relief of excess body pressure are standard feature of this seat design. Slab Gate valve design minimizes and eases the maintenance allowing for the service operations to be done without the removal of the valve from the line.

SAFETY
One of the most important features of synthetic winch lines is the safety benefits they provide. Synthetic lines do not store energy while under load and are very lightweight. This means that if something should go wrong and the rope breaks, it will harmlessly fall to the ground. Steel wire rope on the other hand, stores a tremendous amount of energy under load, and in the case of breakage, will violently snap back and whiplash. This can cause serious injury to people involved in the winching procedure.
Synthetic winch lines don`t have any wire splinters or burrs like steel wire ropes commonly do, so there is no chance of getting a surprise hand injury while handling a synthetic line.

Slab gate valve are manufactured with a full bore, slab gate, rising stem OS&Y and floating seats. Slab gate is a simple solid gate design, featuring metal-to-metal seal between gate and seats, to apply for the most severe service condition, including corrosive and abrasive fluid environments. A floating seat is designed to match the slab gate. A belleville spring and O-ring between each seat and body ensure a tight seal against the slab gate. The floating slab gate uses the natural force of line pressure to obtain a dynamically tight downstream seal in high-pressure differential applications. Low-pressure sealing is accomplished with an o-ring that energizes the seat and minimizes corrosion and debris build up. Common trims are available.

STRENGTH
Synthetic winch lines have breaking strengths 30-90% higher than steel wire rope. This is a tremendous increase and allows for smaller diameter winch lines to be used when switching to synthetic, therefore increasing the amount of line that can be installed on the winch.
WEIGHT
Synthetic winch lines are up to 80% lighter than steel wire rope. Aside from the safety benefits mentioned above, this offers some obvious advantages. On a typical recreational off road vehicle, switching to a Synthetic Winch Line and an Aluminum Hawse Fairlead will shave up to 30 pounds of weight from the front of the vehicle. Rigging vehicle extractions is also much easier, especially in loose, hilly terrain. Synthetic winch lines are so light, they even float.
