Modelo DA5
Back Pressure Regulator
SKU#:
Modelo DA5
Description
The Model DA5 is a high performance, spring operated, back pressure regulator with top-guided piston-cylinder that provides high flow capacity and high pressure drop capability. Internal trim design allows the same basic unit to cover a broad range of pressure settings. Performance approaches that of competitive pilot-operated designs in the basic design. Applied primarily in clean gaseous service, but also can be applied as a liquid or steam valve.

Features
- Versatile: Five basic materials and multiple trim material combinations to select from.
- Tight Shutoff: Multiple composition materials provide Classes II, IV or VI inboard leakage rates. Designed as a soft-seated valve.
- Capacity: Highest in the industry. Allows smaller body sizes than competitors in a majority of applications.
- Pressure Drop: Highest in the industry when coupled with high flow capacity.
- Trim Design: "DO-ALL" trim design provides FTO flow direction. Results in high sensitivity and stability. Internals are cage-contained within easily removable quick change trim.
- Rangeability: Basic valve gives outstanding rangeability due to close tolerances, balanced
trim, and a broad range of elastomeric diaphragms and soft seats. Can be as high as 500:1. - Heavy-Duty Guiding: Heavy top guided to maintain stability and increased diaphragm life.
