Manfaat dan Keunggulan Utama
-
Tight Shutoff: Engineered with high-quality seating materials that ensure a positive, bubble-tight seal. This prevents gas leakage and nuisance venting during normal operating pressures, conserving fuel and reducing odor complaints.
-
Simple Adjustment: The relief setpoint is easily adjusted by a single screw on the top of the spring case. This allows field technicians to quickly calibrate the valve to the specific requirements of the installation site.
-
Complete Venting: The design ensures that once the setpoint is exceeded, the valve opens fully to provide high-capacity relief. The vent is designed to discharge gas efficiently, ensuring that system pressure stays within safe limits.
-
Easy Maintenance: The 1805 Series is designed for “in-line” service. The internal parts can be inspected, cleaned, or replaced without removing the valve body from the piping, which significantly reduces maintenance costs and labor.
-
Sour Gas Service Capability: For applications involving wellhead gas or environments with hydrogen sulfide (H2S), the 1805 Series can be specified with NACE-compliant materials to ensure long-term structural integrity and safety.
-
Durable Construction: Built to withstand the harsh conditions of outdoor farm tap sets, including extreme temperature fluctuations and atmospheric corrosion.
Properti Teknis
-
Relief Pressure Range: Available in various spring ranges from 5 to 125 psig (0.34 to 8.6 bar).
-
Maximum Emergency Pressure: Capable of handling up to 150 psig (10.3 bar) including build-up, providing a significant safety margin.
-
Media Compatibility: Natural gas, propane, air, and other compatible gases.
-
End Connections: Typically available in 3/4-inch and 1-inch NPT threaded connections.
-
Material Options: Offered in Cast Iron and Steel bodies with specialized internal trims for sour gas or standard service.
Bidang Aplikasi
The 1805 Series is a staple in rural gas distribution networks where high-pressure transmission lines are tapped for local use. Its reliability makes it a trusted component for protecting small-scale gas infrastructure.
Industri Primer dan Pemanfaatannya:
-
Farm Tap Installations: Providing essential overpressure protection between the high-pressure primary regulator and the low-pressure secondary regulator.
-
Agricultural Gas Systems: Protecting irrigation engines, grain dryers, and heating systems in remote areas.
-
Gas Distribution: Used as a secondary relief valve in district regulating stations and small municipal gas loops.
-
Industrial Air Systems: Providing simple and effective relief for small-volume compressed air headers.
