PEECO Flow Switches

High Pressure Flow Switches

Rated to 10,000 PSI — All Stainless Steel or Any Machinable Metal

PEECO high pressure flow switch

PEECO High Pressure Flow Switches — To 10,000 PSI

PEECO high pressure flow switches extend the proven PEECO flow-actuated mechanism to extreme pressure service — up to 10,000 PSI. The heavy-wall body and reinforced internals are constructed from all 316 stainless steel as standard, with any machinable metal available for corrosive or exotic fluid service.

Like all PEECO switches, the high pressure model is actuated by flow velocity — not pressure differential — making it insensitive to pressure fluctuations. Each switch is custom-engineered for the application. Explosion proof enclosures are available for hazardous locations.

Pressure Range Selection

Up to 600 PSI
Standard non-explosion proof or explosion proof models
600 – 3,000 PSI
High pressure series — heavy-wall body, reinforced internals
3,000 – 6,000 PSI
Ultra-high pressure — all 316SS, special sealing
6,000 – 10,000 PSI
Maximum pressure series — custom-engineered per application

Available Materials of Construction

316 Stainless Steel

Standard for high-pressure service. Excellent corrosion resistance for most process fluids.

Monel 400

For seawater, hydrofluoric acid, and reducing acids. Superior corrosion resistance.

Hastelloy C-276

For highly corrosive environments including oxidizing acids, chlorides, and wet chlorine.

Inconel 625

For high-temperature, high-pressure, and highly corrosive service.

Titanium

For seawater and chloride-containing environments where maximum corrosion resistance is required.

Custom Alloys

Any machinable metal available — specify fluid and conditions for material recommendation.
