Product Q&A
Q:How does the valve work?
A:
Spring-loaded safety valves operate via a precision spring-and-disc mechanism. In normally closed (NC) mode, the valve remains sealed until system pressure exceeds the pre-set threshold, lifting the disc to release excess pressure. In normally open (NO) mode, the spring holds the disc open for continuous flow, closing only when pressure drops below a threshold or external actuation is applied.
Q:What materials are used for the valve body and parts?
A:
The valve is constructed from robust materials including carbon steel, stainless steel, and alloy steel. Specific parts use materials like Ht350, ZG1Cr18Ni9Ti, 20Cr13, 50CrVA, and 45, with sealing surfaces coated with D507 stellite for durability.
Q:Can the pressure setting be adjusted?
A:
Yes, the valve features adjustable spring tension. This allows for precise matching to the system's Maximum Allowable Working Pressure (MAWP), ensuring accurate pressure relief or flow control.
Q:What are the available operational modes?
A:
The valve offers two configurable default states: normally open (NO) for continuous flow or ventilation, and normally closed (NC) for overpressure protection. This enhances application flexibility for diverse industrial needs.
Q:Is external power required for operation?
A:
No, the valve is self-actuated. It operates entirely via spring force and system pressure, requiring no external power source.
