View Product DetailsPhiladelphia, Pennsylvania, supports one of the most historically robust and diverse industrial landscapes on the US East Coast. Anchored by the Delaware Valley refinery complexes, extensive chemical manufacturing corridors, and complex municipal water structures overseen by agencies like the Philadelphia Water Department (PWD), the demand for high-reliability flow containment is paramount.
Valves installed within these facilities face demanding conditions: coastal air corrosion, chemical runoffs, high-temperature steam lines, and high-pressure water transmission grids. Modernizing this infrastructure requires manufacturers that produce valves strictly complying with AWWA (American Water Works Association), ANSI (American National Standards Institute), and ASME (American Society of Mechanical Engineers) certifications.
As a global partner, KR VALVE designs, manufactures, and tests premium-grade gate valves to guarantee zero-leakage performance under extreme workloads, ensuring security and system reliability for Philadelphia operators.

Gate valves are essential isolation components designed for fully open or fully closed service. In complex municipal pipelines like those in Philadelphia, selecting the correct design—such as rising versus non-rising stems, or resilient versus metal-seated gates—is critical for system longevity.
Rising Stem (OS&Y - Outside Screw and Yoke): Widely specified for above-ground plant applications, chemical processing, and refinery piping in the Philadelphia area. Because the stem thread is kept outside the flow path, it is protected from fluid-induced corrosion, and operators can immediately see the valve position. It requires additional vertical space to open.
Non-Rising Stem (NRS): Recommended for underground vault installations, trench bury situations, and spaces where vertical room is limited. The operating threads engage the wedge inside the fluid envelope, making robust materials like brass or stainless steel essential for the stem nut.
Resilient Wedge Gate Valves: Built to meet AWWA C509/C515 standards. The ductile iron wedge is fully encapsulated in EPDM or NBR rubber. This design offers a bubble-tight seal at low pressure and easily tolerates minor pipeline debris without leaking. It is the standard choice for drinking water distribution.
Metal Seated Gate Valves: Designed for high-temperature and high-pressure systems. These valves use steel or bronze seating rings on the body and wedge to withstand abrasive materials and steam lines, commonly found in power generation and chemical refinery systems.
