Peter Paul Magnetic Latching Valve Model MLV828 (IP)

PeterPaul single orifice valves, in which the orifice is closed in the de-energized position and no flow can exist between the inlet and outlet ports, include a large orifice, internally piloted 2-way normally closed valve. These valves are designed to meet process industry requirements for high flow rate or quick dump and fill capacity. Suitable for gas and liquid applications, these DC-powered valves offer port sizes for pilot lift versions ranging from 1/2” to 3” NPT, with pressure ratings from 3 to 200 PSI.

Large orifice sizes for high flow applications.
Body is made of brass forgings or 316 stainless steel.
Operates on differential pressure — Internal Pilot.
NPT threaded connections.
Same coils and housings as our popular 20 Series.

Operating Conditions:

Media: Air, water, and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require other seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
Valve Temperature Range:
- Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient; 0°F (-18°C) to 150°F (65°C) media.
- Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*
Maximum Operating Pressure Differentials: See table above.
Burst Pressure: 5,000 PSI
Leakage: Bubbletight (with polymer sealing pins)
Vacuum: To 5 Microns*
