Straight-through Type - FAQ
What makes straight-through type designs superior to conventional valve configurations?
Straight-through type configurations eliminate flow restrictions by providing a direct, unobstructed path for fluid movement. This design minimizes turbulence, reduces pressure drop by up to 70% compared to standard valves, and prevents particulate accumulation. The streamlined flow path also decreases wear on sealing surfaces, extending component life.
How does the straight-through type handle high-viscosity fluids?
The straight-through type excels with viscous fluids due to its uninterrupted flow path that prevents stagnation points. The full-bore design maintains laminar flow characteristics even with viscosities up to 500,000 cP. Specialized coatings can be applied to the flow path for additional protection against adhesive buildup in extreme viscosity applications.

Installation Guidelines
| Step | Procedure |
|---|---|
| 1 | Ensure proper alignment of piping before installation |
| 2 | Use appropriate gasket material for media compatibility |
| 3 | Tighten flange bolts in star pattern to recommended torque |
| 4 | Perform pressure test before system operation |
What maintenance is required for straight-through type components?
Straight-through type designs require minimal maintenance due to their simple construction and lack of moving parts in the flow path. Recommended maintenance includes annual inspection of sealing surfaces, verification of actuator function (if equipped), and cleaning of flow passages when handling particulate-laden fluids. Most straight-through type installations operate maintenance-free for 5+ years in standard applications.
