The RV10’s 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.
