#CMT# #/CMT# The valve comprises at least one cover (2); at least one seal (3); at least one casing (1) containing one or more bores (25); at least one movable part (4) with at least one inner seal (9), at least one outer seal (10) and at least one spring (12) for positioning the part in one direction; at least one stem (6) with at least one closure part (13) and having in its upper portion at least one top bore (16), at least one opening (14) and at least one seal, and having at least one opening (19) beneath the closure part and also having at least one bottom bore (17) and at least one opening (18) in its lower portion, seals (20, 21) being provided above and below the latter opening; at least one spring (7) beneath the stem for pressing the stem in the opposite direction, in order to press the closure part against the seal in the upper portion of the stem, so that the opening in the top of the closure becomes blocked; at least one product chamber which can be filled by a flow of product via the bottom bore and the openings in the lower portion of the stem, depending on the stem position; and at least one pressure chamber. Moving the stem in the opposite direction causes the opening in the bottom of the stem to become closed by the upper seal and the opening in the top of the closure part to become exposed, which in turn results in the pressure acting against the movable part via the bore in the pressure chamber to be greater than that exerted by the spring, and the movable part is displaced towards the other side of the product chamber, forcing the product out through the opening in the top of the closure part and top bore. #CMT#USE : #/CMT# For dispensing dosed quantities of liquids, viscous products, pastes and powders (e.g. water, aqueous products, dairy products, desserts, edible and industrial oils, dressings, alcohol, beverages, syrups, gels, cremes, inks, pigments, dyes, paint, varnish, adhesives and other industrial, cosmetic, foodstuff or pharmaceutical products) from a pressurized vessel. #CMT#ADVANTAGE : #/CMT# The product can be dosed more accurately without air entering the system and affecting product quality and sterility. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a cross-section of the valve. 1 : Casing 2 : Cover 3, 9, 10, 20, 21 : Seals 4 : Piston 6 : Stem 7, 12 : Springs 13 : Closure part of stem 14 : Opening in top of closure part 16 : Top bore 17 : Bottom bore 18 : Opening in bottom of stem 19 : Opening leading to product chamber 25 : Additional bores. |
