4.3 Gate Valves
4.3.1 Function of gate valves with bolted bonnet
The valve consists of the pressure-retaining parts, i.e. body 100 and yoke 166, and the
functional unit.
Body 100 and yoke 166 are connected by studs 902.1 or grub screws 904 and nuts
920.1, and the joint is sealed off by joint ring 411.1.
4 Valve Description
15 of 68
The functional unit consists mainly of wedge holder 367, flexibly mounted wedge
discs 360 and stem 200. The actuating element is either a handwheel 961 or an
actuator.
The seating faces of body 100 and wedge discs 360 are hard-faced. Gland packing
461, which seals off stem 200, is tightened via gland follower 452 by means of studs
902.3 or hinged bolts and nuts 920.2.
4.3.2 Function of gate valves with pressure seal bonnet
Gate valves with wedge discs 360 consist of body 100 with welded stellited seat rings
515, wedge discs 360 with stellited seating faces, bonnet 139 with gland packing 461
and yoke 166 with the actuating element.
Shut-off is performed by two wedge discs 360 pressed against seat rings 515; they are
flexibly mounted in wedge holder 367 and supported by replaceable thrust inserts
553 via pins 563.
Wedge holder 367 is screwed onto stem 200. A retainer prevents wedge discs 360
from twisting in wedge holder 367. To prevent twisting of the obturator
components, the wedge holder is guided in the body by lateral guide ribs 752. The
valve is equipped with a pressure seal bonnet.
The pressure inside body 100 presses bonnet 139 against joint ring 411.1, which is
supported by compression ring 501. The studs 902.2 and hexagon nuts 920.6, which
are supported by thrust plate 414 ensure that bonnet 139 is held in position against
joint ring 411.1, even if there is no pressure inside body 100.
For fitting a body pressure relief valve (ðSection4.4.1,Page29) (see type series
booklet 7300.1) a 22/14x74mm connection branch 131.2 is welded to body 100. The
connection branch is closed upon delivery.
Body pressure relief valves, if ordered, are supplied unassembled, i.e. attached loosely
to the gate valve.
Instead of fitting a body pressure relief valve, the operator may also provide a means
of pressure balancing between the body's middle section and the gate valve's
pressurised connection branch, e.g.:
▪ a pressure balancing hole in the seat ring or
▪ an external balancing line.
In this case the gate valve can be used for one flow direction only.
If gate valves and swing check valves in pressure seal design (bonnet 139) are fitted in
close proximity to one another, meaning that the trapped liquid could heat up if the
valves are closed, the operator must fit a body pressure relief valve.
Gland packing 461, which seals off stem 200, is tightened via gland follower 452 by
means of studs 902.3 and nuts 920.1. Stem 200 is moved in axial direction by the
rotating threaded bush 544, which is fitted with cylindrical roller bearings 323. Stem
200 lifts off wedge discs 360 or presses them against seat rings 515.
Threaded bush 544 is positioned in the yoke head by intermediate flange 729 and
hexagon socket head cap screws 914.1. Handwheel 961 sits on threaded bush 544, to
which it is joined via key 940. It is secured by circlip 932.
The stop nut 920.3 fitted on stem 200 serves as a travel stop in closing direction. It
prevents jamming of the wedge assembly in the seat and is secured by parallel pin
562.3.
Fig.2: Parallel discs
Unlike wedge gate valve designs, slide gate valves feature two parallel discs 368,
which are flexibly mounted in disc holder 367. The discs are supported by replaceable
disc springs 950.1 via parallel pins 562.1, which press them against seat rings 515.
