I. GENERAL INFORMATION
DESIGN
All WMK 370D5 Ball Valves are non-directional and can be installed with either end
upstream. Flanged-end valves (sizes 24” and smaller, except 22”) have flanges faced and
drilled in accordance with ASME B16.5. 22” and sizes 26” and larger conform to MSS
SP-44. Face-to-face and end-to-end dimensions conform to API Spec. 6D, Table 4.4,
“Flanged-End and Welding-End Ball Valves Full Port and Reduced Port.”
BLOCK-AND-BLEED
All current 370D5 valves have body drain ports per MSS-SP-45, i.e. 3/4” NPT for 6-8” valves
and 1” NPT for 10” and up. A special vent valve is supplied as a standard feature for
block-and-bleed service.
EMERGENCY SEAT SEALANT SYSTEM
1/2” NPT steel fittings with giant button heads are installed in the mid-section of both
closures. On valves 22” and larger, dual fittings are provided on both the front and back
side of the valve. Section III-C describes the function of the sealant system.
FIELD WELDABILITY - WELDING END VALVES
WKM ASME Ball Valves with welding end connection(s) utilize ASTM A36, A572 Gr. 50,
A537, A216 Gr. WCB, A350 LF2, A105 and A106 Gr. B steel. All are readily field weldable.
When welding 370D5 valves in the line, standard field welding techniques and procedures
are satisfactory.
BODY RELIEF VALVE
To protect the body from thermal over-pressure in above ground liquid service when
valve is in the closed position, a 1/2” NPT steel body relief valve, located in the upper body
area, is furnished. It has been factory adjusted to a nominal relief setting of 1.6 x rated
pressure. A small hole in the ball equalizes Line pressure and body pressure when the
valve is in the open position.
II. VALVE INSTALLATION
A. EQUIPMENT
Handling equipment is required for the weight involved. The current 370D5 Ball Valve
catalog furnishes the weight of the specific valve.
B. PROCEDURES
1. Remove end connection protectors.
2. Inspect valve port for foreign matter and clean, if necessary. Valves are shipped
with ends sealed, but during transit foreign material may be introduced into the
port.

3. Install in line; either end may be installed upstream.
4. Install vent valve, if not already factory-installed.
5. On valves having extensions, check all extension piping and fittings to ensure that
all are tight prior to placing valve in service.
6. The seat sealant system is intended only for emergency shut-off. Do not lube.
(See Section III-C).
III. ON STREAM MAINTENANCE
This part covers maintenance and repair which can be performed without removing the valve
from the line.
A. BLOCK-AND-BLEED
With the line under pressure the valve body cavity can be vented to atmosphere and com-
pletely drained down with the ball in the CLOSED POSITION ONLY.
The valve body cavity may be drained and flushed by:
1. Removing the special vent valve after pressure has been vented.
2. Removing the 1/2” NPT relief valve from the upper body area.
3. Flushing through upper relief valve connection and allowing drainage through the
lower vent plug connection.

10.Crack valve to allow body to repressure to check
Integrity of the new seal.
C. EMERGENCY SHUT-OFF
The seat seals of all 370D5 valves are designed not to
require sealants; however, in the presence of excessive line
contaminants, the possibility of leakage, due to erosion, is
greater than when a valve is used for normal on-off service.
If the metal-to-metal primary seal and the secondary O-Ring
seal are damaged, an emergency shut-off may be obtained
with a sealant injected into a specially designed groove in the
seat ring assembly. This feature is especially important in
critical under-water applications where it may be impractical
to remove a valve from the line. WKM 370D5 valves are
equipped with fittings for emergency sealant injection. We
ship without sealant fittings and drain valves for subsea
service.
SEALANT INJECTION INSTRUCTIONS
First purge the sealant passages by injecting "SEALWELD"
VALVE CLEANER (or equivalent). This operation purges old
greases and residual build-up which contribute to seal
leakage and excessive operating torque.
With valve in the fully closed position, slowly inject "SEALWELD
911" sealant (or equivalent) through the large buttonhead
fitting provided on the upstream closure. If possible, move
ball slightly during injection to ensure that sealant is evenly
distributed over the sealing surfaces of the seat ring and
the ball. (For ball valves with damaged balls or seats use
"SEALWELD" BALL VALVE SEALANT NO. 5050, or equivalent).
For low temperature services down to -75 to +400 degrees
Fahrenheit, use "SEALWELD" VALVE SEALANT D-1014 (or
equivalent). A damaged sealant fitting may be removed
and replaced while the valve is under pressure, by first
injecting a small amount of sealant to ensure the tightness
of the single or double ball check valve installed in the
sealant passage under the grease fitting.
D. IN-LINE HYDROSTATIC TESTING
1. With zero pressure in the line and in the valve,
remove the relief valve and replace with a pipe plug.
2. Make sure that vent plug valve at bottom of valve is closed.
3. On valves 14" and larger, remove the body vent plug
from the gland plate to permit evacuating all air from
body cavity.

4. Open ball valve about 1/3 to permit pressurizing valve
body.
5. Fill line and valve body until liquid flows from
gland plate body vent port and pressures the
relief port.
6. Raise pressure to desired hydrostatic test pressure.
This pressure must not exceed 1-1/2 times the maximum
operating pressure of the valve - unless prior approval
to test at higher levels is obtained from Engineering.
7. After test is completed:
a. Close ball valve.
b. Vent any remaining body pressure through bottom
vent plug valve and close tightly.
c. REINSTALL THE RELIEF VALVE
This is very important for protection of the body
against over-pressure when the valve is in the
closed position.
CAUTION: DO NOT ALTER THE RELIEF VALVE SETTING.
8. When valve is in the closed position, test pressures
must NOT exceed the maximum rated operating
pressure on the valve.
