Claim:
1. A gate valve assembly for perpendicular mounting to a cylindrical pipe, the gate valve assembly comprising: a nozzle including an open distal end and an open proximal end with a through passage extending from the distal end to the proximal end, the proximal end perpendicularly connected to a upper saddle member, the upper saddle member coupled to a lower saddle member for clamping the cylindrical pipe therebetween, the passage further including a distal portion having a first non-circular cross-sectional profile that extends from the distal portion to a proximal portion having a first circular cross-sectional profile, a gate valve comprising a cartridge and a paddle, the cartridge including a distal section connected to a proximal section, the distal section of the cartridge having a second non-circular cross-sectional profile that is mateably and slidably received in the first non-circular cross-sectional profile of the passage of the nozzle, the first and second non-circular profiles blocking rotation of the cartridge when the distal section of the cartridge is received in the passage, at least part of the proximal section of the cartridge having a second circular cross-sectional profile that is mateably received in the first circular cross-sectional profile of the passage, the proximal section of the cartridge further including a rounded proximal end, the proximal section of the cartridge including a paddle recess that extends along diametrically opposite portions of the proximal section and diametrically across the rounded proximal end of the cartridge, the paddle recess accommodating the paddle, the first and second non-circular cross-sectional profiles orienting the paddle recess and the paddle in a perpendicular relationship to the cylindrical pipe.
