Overview

Parallel Slide double disk Gate valves are designed with independent discs and wide flat seats. The wide flat seats in our gate valves assure a flat, close contact with the disc which creates a long difficult path for any incipient leakage. The wide seating surfaces are designed to reduce seat bearing stress and guarantee long life. They also minimize the effect of minor damage to the surface as sealing occurs over the entire surface



Features

1.Anti-Rotation Device and position indicator eliminate torque wear of seats. Prevents stem turning and indicates valve position;

2.Two piece packing gland loads packing evenly, reducing possible damage to the stem;

3. Tight reliable closure of the cover is assured by the use of our graphite seal ring. Graphite seal ring allows quick access to internal parts. Accommodates minor variations in mating parts where metal seals will not. Lower cost for replacements;

4. High strength heat treated stainless steel stem with backseat;

5. Wide, flat seating surfaces are relatively immune to minor damage that can easily cause leakage in valves that utilize line contact seating;

6. Slight wiping action of the disc removes foreign matter from the seat. Rotating disc movement distributes wear evenly over the whole working surface. Completely removed from the flow passage when open. Self aligning, interchangeable discs assure tight shutoff and long life.

7. A light, non-corrodible spring keeps the discs in close contact with the seats when the valve is not under pressure.
