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
