ประโยชน์และข้อดีที่สำคัญ
-
High-Temperature Capability: Engineered for service up to 550°F (288°C), making it one of the few pilot-operated relief options suitable for high-pressure steam and hot process liquids.
-
Superior Chemical Resistance: Offers a wide array of chemically compatible elastomers, including Perfluoroelastomer (FFKM) and high-temperature EPDM. These options provide excellent resistance to heat and aggressive corrosive chemicals.
-
Class VI Shutoff: Even at high temperatures, the use of specialized elastomers ensures a bubble-tight, ANSI Class VI shutoff, preventing product loss and maintaining system pressure during normal operation.
-
Fast Speed of Response: The pilot-operated design allows the main valve to respond rapidly to pressure spikes, ensuring immediate relief to protect downstream equipment or upstream process integrity.
-
NACE MR0175/MR0103 Availability: Construction materials can be specified to meet NACE requirements for sour gas environments, making it ideal for upstream oil and gas production.
-
Versatility: A single valve platform that performs equally well in liquid, gas, or steam service, simplifying spare parts inventory and engineering specifications across a facility.
-
Easy Differential Conversion: The 912 Series or other pilot configurations can be easily modified for differential pressure control, allowing the valve to maintain a set pressure difference between two points in a process.
-
Durable Construction: Available in a variety of robust materials, including Stainless Steel and Carbon Steel, to match the metallurgical requirements of the piping system.
