Advantages of the SOURCE Design
The VERSA GATE VALVE series offer an economical field proven oilfield
valve for the oil & gas industry. A choice of versa-slab and versa-wedge gates
is available which are purpose designed to maximize usage of common parts
such as the universal valve body and bonnet assembly to afford an overall
cost effective valve . The versa gate valve line of products are designed and
manufactured to the latest requirements of API 6A specifications and API
Q1/ISO9001 quality assurance.
Metal to Metal stem
backseat sealing
allows stem packing
replacement with
valve under pressure.
Metal to Metal
seat/body and
seat/gate sealing.
Packing design for different
services temperature,
pressure and drilling and
production fluids.
For PR1 service, standard
elastomeric seal packing is
used.
For PR2 service, special
design non-elastomeric SV
stem packing is used.
SV stem packing provides
an excellent service for
chemicals in oil and gas
production fluids.

Operating & Service Manual 1 OPS-804 Rev.01
Section 1 Warnings
The VERSA-SLABTM–LS Gate Valve is a bi-direction non-rising stem manual operated valve incorporating a
floating gate and seats design. The gate is connected to the stem through a barrel lift nut in the gate. This
arrangement permits the gate to float freely and enhance a pressure assisted seal when acted on by the
differential pressure across the gate. Constant contacts behind the gate and seats are maintained by action of
wave springs located behind the seats and help to keep debris from accumulating into the valve cavity.
The bonnet is bolted to the valve body and pressure integrity is achieved by means of a metal ring gasket.
Pressure energized U-type stem packing are used to isolate pressure in the valve cavity. The stem has a
selective back seat feature to facilitate replacement of stem packing in the field when the valve cannot be
removed from service.
The gate is actuated by rotation of the stem-opening (counter-clockwise rotation) and closing (clock- wise
rotation). The bearing spacer is sandwiched by needle bearing assembly to provide a sturdy low operating
torque gate valve.
The bonnet is equipped with a ½” grease/injection fitting for lubrication of the valve cavity and the bonnet cap
has a standard grease zerk for lubrication of the stem bearing assembly.
ALL OPERATORS AND MAINTENANCE PERSONNEL SHOULD BE THOROUGHLY TRAINED IN THE SA-
FE OPERATION, MAINTENANCE, AND INSPECTION OF THIS EQUIPMENT.

Section 2 General Operation
2.1 General Description
The VERSA-SLABTM–LS Gate Valve means closing member (shutter) movable in the vertical direction of the
channel axis of the valve, the pipe is mainly used as cutting medium effect, i.e., fully open or fully closed use.
As the throttle valve is generally not used. It can be used in high temperature and high pressure, and can be
used in various media.
Rotate stem clockwise to "close", counterclockwise to "open".

Breaking Torque denotes torque applied to open valve at full differential rated working pressure.
Running Torque denotes torque applied to operate valve after pressure is equalized across the gate.
NOTE:
It is important to back off ¼ turn after fully opening or closing valve. This is to allow the gate to freely
float acting on by line pressure.

Section 3 Assembly Procedure
3.1 Installing Seat Assembly to Valve Body
a) Thoroughly clean the internal of valve body.
b) Lightly grease seat and install lip seal on the side of groove towards wave spring end of seat.
c) Coat the seat pockets in the valve body with grease.
d) Carefully press seat assembly evenly into the seat pockets, wave spring facing inside of pocket.
e) Place bonnet gasket on valve body and makeup the flange blots or studs into the valve body.
NOTE:
For tap end stud, the shorter end is installed to valve body.

Operating & Service Manual 4 OPS-804 Rev.01
3.2 Installing Bonnet Assembly
CAUTION:
The stem bearing assembly must be firmly lock down by the bonnet cap against the packing gland to
operate properly. Any slack or clearance in the bearing spacer, bearings due to improper assembly
would affect the operating torque as the needle bearings would no longer working effectively.
a) Lightly grease stem and install to bonnet from the bottom.
b) Lightly grease stem packing and slip over stem and evenly press them into bonnet cavity. Ensure no gr-
ease or water is trapped between to two packing. (Note: Stem Packing should be installed with U-cup
side facing down into bonnet pocket)
c) Install packing gland over stem and make up to bonnet. The packing gland should be sitting butt tight on
top of bonnet.
d) Install bearing assembly and bearing spacer over stem and insert thrust pin through bearing spacer and
stem. Rotate stem until stem/bearing assembly sits firmly on top of packing gland.
e) Install the bonnet cap over the stem and make up snugly tight to bonnet.
3.3 Install Gate to Bonnet Assembly
a) Lightly grease the barrel lift nut and insert to the gate. Carefully make up gate assembly to the stem by
left hand rotation, until the stem has fully engaged the lift nut and partially penetrate the gate.

Operating & Service Manual 5 OPS-804 Rev.01
b) Lightly grease the 2 sealing faces of the gate.
3.4 Installing Bonnet/Gate Assembly to Valve Body
a) Carefully lift bonnet/gate assembly over the valve body and stab the gate in the space between the seats.
A seat spreader aid may sometimes be necessary to spread the seats to make it easier for installing the
gate. Once the gate has started between the seats it would easily slide all the way down until the bonnet
comes into contact with the valve body.
