The RV10 safety relief valve is well-suited for overpressure protection of production equipment, including compressors, scrubbers, separators, pipelines or anywhere overpressure protection may be required. The design incorporates a non-rising stem to give the disk full guidance while opening and closing. The non-rising stem coupled with the valve’s soft-seat design ensures long-lasting set pressure repeatability and bubble-tight shutoff. The shorter stem also makes the valve more compact, making it ideal for requirements where space may be an issue.
