Liquid and Gas Controls For A New Level of Success. Established in Oklahoma
City in 1981, WellMark® began business with a single product line, a
cantilever-style liquid level control. Throughout the following sixteen
years WellMark expanded its offering, adding several
other oil/gas production-related products. By 1997 we
had acquired CEMCO/Major, two companies who were well
respected in their own rights, expanding their product
offering even further. Today, WellMark® produces a
comprehensive range of liquid and pneumatic controls and valves.
WellMark® continues to lead the way, helping oil and gas
producers meet their EPA Natural Gas STAR Program or
Kyoto pledge of reducing methane emissions by developing
environmentally-conscious alternatives to conventional
high-bleed pneumatic control devices. These include the
industry-renowned MIZER® Pilot Valve – a unique product
which painlessly converts many high-bleed pneumatic
devices to low-bleed. This patented device is licensed
for manufacture exclusively by WellMark and has been
successfully employed by many of the world's major
producers to substantially reduce their methane
emissions, easily and effectively.
These valves are for general purpose gas and air
services, and are recommended for over-pressure
protection on separators, compressors, pressure vessels,
heater-treaters, gathering and transmission lines, meter
runs, and other systems where the rated capacities of
the valve are commensurate with the requirements of the
system. All of these valves are manufactured in
accordance with the ASME Boiler and Pressure Vessel Code
and have been capacity tested and certified by the
National Board to meet the requirements of Section VIII
of the ASME Code, as signified accordingly by the
symbols UV and NB on their nameplates.
This WellMark Relief Valve is for the control of vapor
emissions. It can be used on glycol dehydrator
re-boilers to meet EPA standards, or any situation where
pressure in ounces is to be controlled.
Series 6900 Cemco Style Cantilever liquid level controls
offer design simplicity, easy installation, adjustment,
and reliable liquid level monitoring. It is a highly
efficient device for the control of liquid level in oil
and gas production equipment such as: separators,
dehydrators, and treaters, as well as in manufacturing
plants, hazardous waste disposal, food processing, water
treatment, petrochemical facilities, or wherever fluid
levels need to be monitored or controlled. The sensing
element design, with no moving parts exposed to the tank
or vessel fluid, makes the simple installation of the
control possible in various standard pipe closures such
as: ANSI flanges and grooved, or union, connections.
These WellMark accessories are for fast,
on-location, pressure checks. Use on wellheads, on flow
lines and on pressure vessels, or wherever repetitive
pressure readings are taken.
WellMark Style control used as a fuel gas control valve to feed the pilot on heated
separators, treaters, and other similar liquid
accumulators, as well as a low pressure, low volume dump
valve on oil and gas production separators, compressors,
or any type of liquid accumulator.
