Abstract

1,117,596. Valves. VELAN ENG. Ltd. 23 July, 1965 [24 July, 1964], No. 31410/65. Heading F2V. The seat grooves provided around the fluid inlet and outlet passages of a rotary spherical valve have a cross-sectional shape as shown with walls 61, 63 joined by an inclined wall 65. Within each groove is an annular seating member 32 having a cross-sectional form with surfaces 50, 51 which abut the walls 61, 63 and two other surfaces 50 and 51 which are concave and substantially convex, respectively. The surface 51 may be arcuate or comprised of two inclined planes meeting at an apex 57. The spherical obturator urges the apex 47 in the direction of the arrow A the resulting deflection causing the seating to bear against its groove along the direction of the arrows B and C. The seatings are of elastomeric material, e.g. nylon or P.T.F.E.
