DSS Product Brochure
Premium Components Come Standard
For starters, all DSS Valves meet or exceed MSS SP-135, and include the following features:
- Wider gates, internal guides, and full bore matching standard pipe sizes
- Energized resilient perimeters with hybrid resilient/metallic seats
- Fully indexable Ni-hard wear rings
- Wider and thicker primary and secondary transverse seals that provide better sealing at higher pressures.
- Dual transverse seals and secondary body seals for 4″ bore sizes and larger
- Thicker primary body seal (10mm for ≥8” bore sizes, 6mm for ≤6” bore sizes)
- Stainless steel screws for dust covers
- Four bolt yokes for valves with 6″ bore size and larger
- Fully supported flanges eliminates the need for pipe nipples on DBB valves
- SAE 660 bronze ACME nuts for smoother operation
- Larger ACME screws for ≥26″ bore sizes
- 17-4ph cylinder clevis pins that are stronger and corrosion resistant
Problems We Solve
PROBLEM: PIPE TURBULENCE & EROSION
SOLUTION
Full Round Bore & Wider Gate and Internal Gate Guides
A round port that matches the pipe ID minimizes turbulence and the resulting erosion. Using wider gates eliminates the flat sides seen with other designs and provides greater support to the gate.
PROBLEM: LEAKAGE TO ATMOSPHERE
SOLUTION
Dual Transverse Seals & Primary and Secondary Body Seals
Ensuring process is contained within the pipeline envelope is the target of operating sites. Using dual transverse seals with a larger packing well ensures zero leakage to atmosphere.
PROBLEM: TRUE ISOLATION DURING CYCLING
SOLUTION
Seal Retention Holes Drilled in Both Body Halves
Seal integrity is paramount in order to achieve isolation. Seal retention holes in both body halves eliminate stretching, tearing and deformation by mechanically retaining the seal. This ensures repeatable zero leakage.
PROBLEM: PIPE STRESS
SOLUTION
Primary and Secondary Body Seals & A Greater Number of Body Bolts
Some degree of pipe stress is unavoidable in large diameter piping systems. Using a greater number of body bolts ensures the body halves maintain the valves integrity under stress, while the primary and secondary body seals combine to provide the highest level of assurance against leakage.
PROBLEM: TOPWORKS STRUCTURE FAILURES
SOLUTION
Heavy Duty Yolks
Other designs on the market often fail at the connection between the topworks structure and the valve. We’ve remedied this issue by performing FEA on these parts to ensure this critical, but often overlooked area is enforced with heavy-duty components along with the right number and size of bolts that attach the topworks to the valve. This means greater safety for operators and a superior thrust platform for pneumatic, hydraulic, electric and electro-hydraulic actuators.
