PCD Series Dual-Valve Pressure Controllers
Fast, repeatable pressure controllers for closed or dead‑ended volumes
The PCD pressure controller features dual valves for fast, precise pressure control in closed or dead‑ended volumes. PCD controllers offer accurate, repeatable control of absolute, gauge, or differential pressure. Vacuum pressure controllers are also available.
- Absolute, gauge, or differential pressure
- For vacuum or positive pressure
- Steady control at 0.01% – 100% of full scale (10,000:1 turndown ratio)
- 30 ms control response
- Limited Lifetime Warranty
Full Scale Pressure Ranges
1 – 3,000 PSI
