Ningjin APC Industries Z45-300A (or Z45-300) is a Non-Rising Stem (NRS) resilient wedge gate valve engineered for space-constrained, high-pressure fire protection infrastructure. Because the stem remains inside the valve body during operation, it is ideal for shallow underground pipelines, wall vaults, and areas with limited vertical overhead clearance.
The Z81-300A (or Z81-300) is an Outside Screw and Yoke (OS&Y) resilient wedge gate valve featuring grooved connection ends. Manufactured by Ningjin APC Industries and engineered for severe-duty fire protection infrastructure, its OS&Y design provides an immediate visual confirmation of whether the valve is physically open or closed
