NONRISING STEM GATE VALVE.

Fig. 719H

It is manufactured in sizes from 2" to 36". The body has 85-5-5-5 brass seats, as well as the disc and gate; the contact of the faces, which these seats, make gives us the scaling of or perfect closure of the valve. The bonnet seals with the steam when the valve is completely open, and this permits the valve to be repacked by pressure.

The body has guides on both sides, which facilitate the sliding of the gate, thus obtaining, that the seats seal perfectly; the union between the head and body is obtained by means of screws and nuts, having between then a compressed asbestos gasket.

The brass stem, is finely machined and threaded with ACME screw threads, and is coupled with the gate or disc, by means of a brass 85-5-5-5 screw; when the valve is completely open, the running of fluids will be completely free. This valve is manufactured according to the NOM H-8 1980, standards of The Head Office of Standards, and guaranteed for one year, only for defects in manufacture.

NOTE: When you press a number on the valve plane the description about this will appear at the top of the screen
