Watts (1/2 LF263A 50-175) Small 3-Way Water Pressure Regulator 1/2" NPT 50-175
Small 3-Way Water Pressure Regulator LF263A 50-175
Compact brass pressure regulator for general purpose water systems. Adjustable 50-175 PSI range with 1/2" NPT threaded connections and integrated gauge port for precise control in beverage equipment, ice machines, and small process applications.
Built for Small Applications That Need Reliable Pressure Control
Oversized Orifice Design
Larger internal passage than standard regulators ensures consistent flow rates for beverage dispensers, paint sprayers, and ice cube machines without pressure drop.
Tee Handle Adjustment
Easily adjust outlet pressure between 50-175 PSI without tools. Aluminum spring cage protects internal components while allowing quick field adjustments.
Reinforced Diaphragm
Buna-N reinforced diaphragm with stainless steel disc provides reliable pressure sensing and long service life in potable water and No. 2 fuel oil applications.
Integrated Gauge Port
1/4 inch 2-way low-pressure gauge port allows continuous pressure monitoring without additional adapters or tees in the line.
Brass Body Construction
Lead-free brass body with NPT female threaded inlet and outlet connections. Rated for 300 PSI maximum working pressure for commercial-grade durability.
Ideal Applications for the Watts LF263A
The Watts Series 26A Small Pressure Regulator works in beverage dispensing systems, paint spraying equipment, ice cube machines, commercial humidifiers, drinking fountains, and small process applications requiring stable inlet pressure reduction. Compatible with potable water and No. 2 fuel oil. Use with upstream strainer recommended for optimal performance. Available with optional Viton trim for specific chemical compatibility or slotted adjusting screw for tamper resistance.
Service Intervals for Pressure Regulators
Pressure Check
Verify outlet pressure with gauge. Adjust tee handle if needed to maintain target PSI range for your application.
Upstream Strainer
Clean or replace upstream strainer element to prevent sediment buildup that can affect regulator performance and accuracy.
Diaphragm Inspection
If pressure fluctuates or regulator fails to maintain setpoint, inspect Buna-N diaphragm and disc for wear or damage.
Commercial Grade
300 PSI maximum working pressure with brass construction for demanding installations
Wide Adjustment Range
50-175 PSI adjustable outlet covers most small appliance pressure requirements
Gauge Ready
Built-in 1/4 inch gauge port for easy pressure monitoring without additional fittings
Lead-Free Certified
Watts LF series meets lead-free requirements for potable water applications
