CONTROL VALVES
Welker began with control valves and is still recognized for control
valve designs that offer unlimited flexibility. The Welker JetŪ Control
Valve offers a design that fits into conventional piping configurations,
an insert style that fits between two standard pipe flanges and a
new top-entry style that provides ease of maintenance while leaving
the valve body in the pipeline. The straight through flow path and
high-recovery design make the Welker Jet applicable in all types of
gas control installations. |

COMPOSITE GAS SAMPLER
The Welker Composite Gas Sampler, with it's patented Vanishing ChamberŪ
collection head, is used to determine the quality of a flowing stream.
Welker Composite Gas Samplers are the only samplers capable of purging
themselves 100% prior to sample collection regardless of gas quality.
Welker Sampling Systems set the industry standard for accurate and
repeatable measurement. The sampler interfaces with any metering system,
is as accurate as any on-line analyzer and costs only one-fourth as
much. |

HYDROCARBON SAMPLERS
Utilizing a constant pressure system, Welker Light Liquid Hydrocarbon
Samplers can collect, store, mix, transport and inject a composite
sample into any analyzer without changing the phase of the sample.
The sampler's simple design and high reliability ensure 100% integrity
of sample handling. |
 |
CRUDE OIL SAMPLER
The Welker Crude Oil Sampler is the industry's only true isokinetic
design, extracting a sample from he pipeline flow for analysis of
brine, sediment and water content. Major oil companies and petroleum
cargo inspection agencies worldwide rely on the Welker Crude Oil Sampler
for pinpoint accuracy and reliability. The new ELSCS Electric Sampler
is designed for those locations where pneumatic air supplies are not
available. The ELSCS is able to sample into atmospheric and constant
pressure cylinders with the accuracy that you've come to expect from
Welker samplers. |

SAMPLE CYLINDERS
Welker Constant Pressure Floating Piston Sample Cylinders collect
and maintain gas or liquid samples at full pipeline conditions-regardless
of pressure and temperature- and provide collection, storage and transport
of liquid or gas samples at pipeline conditions. D.O.T. approved models
are available for working pressures up to 3600 psi. DNV and Transport
Canada approved models are available in several sizes with working
pressures up to 1800 psi. The recently introduced TRAXX PAK remote
monitoring system allows the customer to monitor several cylinders
from one single location, saving both time and money. The system is
easily retrofitted to existing cylinders or available as an option
on new cylinders. |

PRODUCT SAMPLERS
Welker leads the industry in the design and installation of Refined
Product Sampling Systems. They are engineered for the continuous
and harsh environments of refined product sampling conditions. Each
system is individually designed and built to specific customer needs
and space requirements.
Welker also designs and manufactures a comprehensive line of filters,
regulators, relief valves and other components for instrumentation.
All these, as well as Welker's custom engineered control packages
and chemical injection systems, utilize Welker's innovative technology
and patented designs for the industry. Welker Engineering Company
headquarters - located in Sugar Land, TX - feature over 70,000 square
feet of office and manufacturing facilities. ISO-9001 certified
since 1992, Welker Engineering continues to anticipate and answer
the needs of the oil and gas industries with creative and innovative
measurement equipment.
