主なメリットと利点
-
Simple and Reliable Design: The straightforward mechanical architecture minimizes the number of moving parts, leading to high reliability and reduced potential for failure in remote field locations.
-
Compact and Lightweight: Their small physical footprint makes them ideal for installation on skid-mounted equipment or in tight piping manifolds where space and weight are critical considerations.
-
Installation Versatility: These valves are designed for convenient installation in any orientation, providing engineers with maximum flexibility when designing piping layouts for separators or distribution headers.
-
Self-Draining Body: The internal geometry is designed to prevent the accumulation of liquids, which is essential for preventing ice formation or debris buildup that could interfere with valve operation.
-
Quick Disassembly: Maintenance is simplified by a design that allows for fast disassembly. This ensures that internal inspections and parts replacement can be completed with minimal downtime.
-
Optional Upstream Registration: Can be configured with upstream registration to reduce pressure build-up, ensuring the regulator maintains a tighter control band even during high-flow relief events.
-
Media Versatility: Suitable for use in both gas and liquid service, allowing for standardized equipment across different process streams on a single site.
技術的特性
-
Body Styles:
-
Type 1808: Standard globe-style body for straight-through piping.
-
Type 1808A: Angle-style body, often used to replace a 90-degree elbow in the piping.
-
-
Operation: Pilot-operated for high sensitivity and rapid response to pressure changes.
-
Application: Relief (overpressure protection) or Backpressure (upstream pressure maintenance).
-
End Connections: Available in standard NPT threaded connections for easy integration.
-
Materials: Typically offered in robust materials suited for oilfield and utility environments.
適用分野
The 1808 Series is the go-to choice for upstream oil and gas production and local gas distribution networks. Its blend of economy and performance makes it a staple for mid-range pressure applications.
主要産業と用途：
