Description
Overview
The Type 700 High Flow Pressure Regulator is designed for applications requiring high flow capacity, excellent sensitivity, and stable pressure regulation under varying operating conditions. Utilizing a balanced poppet valve, rolling diaphragm design, and aspirator-assisted flow control, the Type 700 delivers consistent downstream pressure while supporting flow rates up to 80 SCFM.
Unlike conventional pressure regulators that experience significant droop as flow demand increases, the Type 700 continuously compensates for changing flow conditions through its integrated aspirator tube. This design helps maintain stable outlet pressure during dynamic system operation, making it ideal for pneumatic actuators, valve operators, test systems, web tensioning equipment, and industrial automation applications.
The regulator combines high-capacity flow performance with excellent sensitivity and low supply pressure effect, providing reliable pressure control in both OEM and process control environments.

FAQs
What makes the Type 700 different from a standard pressure regulator?
The Type 700 utilizes a balanced poppet valve, rolling diaphragm, and aspirator tube design to provide high flow capacity while minimizing pressure droop under changing flow conditions.
How much flow can the Type 700 handle?
The regulator supports flow rates up to 80 SCFM (2,264 Nl/min), making it suitable for high-demand pneumatic applications.
What is the benefit of the aspirator design?
The aspirator tube automatically adjusts airflow based on flow velocity, helping maintain stable outlet pressure as downstream demand changes.
When should I select a larger port size?
Larger port sizes should be selected when maximizing flow capacity and minimizing pressure loss are critical to system performance.
Can the Type 700 be serviced without removing it from the air line?
Yes. The regulator is designed for online maintenance, allowing service without removing the unit from the pneumatic system.
