COMPRESSOR VALVES Offer Distinct Value The Issues: Common problems associated with compressor valves in natural gas plants include limited service life, high parts usage and costs, availability of replacement parts, plant downtime due to maintenance requirements, and the need for full-time maintenance staff. These factors can negatively impact a company’s bottom line due to decreased cost effectiveness and competitiveness.
		The Solutions: At many natural gas plants in western Canada, Chinook compressor valves have provided benefits. At a major gas producer’s facility, a dramatic improvement was achieved in service life beyond 25,000 hours on high speed units and 40,000 hours on slow speed units. As a result, personnel became available to work in other important areas. Other customers have reported increased gas flow, reduced maintenance costs and parts usage, and significant cost savings on replacement parts.

A History of Success:
Chinook compressor valves have a long and successful history of usage in Canada and are recognized as the Industry Standard for use in the most demanding of applications. Their engineered fine tuning allows for improved aerodynamic flow giving increased efficiency and throughput. Reduced maintenance is a direct result of this unique design. Chinook manufactures compressor valves and component parts to any form, shape or specification as required by the customer. All materials conform to N.A.C.E. specifications for sour gas service. Chinook valves can be easily serviced by our customers’ field personnel or returned to our Calgary plant for guaranteed reconditioning.

Discs, Rings, Plates:
Chinook’s Grade 2516 thermoplastic is our standard material for compressor valve discs. Made of tough, durable material that is highly resistant to chemical attack, its light-weight characteristics have allowed Chinook to design a thick cross section aerodynamic disc which incorporates self-guiding and self-seating features. The low mass of the Chinook compressor valve disc enhances its ability to successfully withstand the shock loading of liquids in the gas stream. Chinook Grade 2516 thermoplastic possesses the ability to heal over abrasive matter while retaining its seal. An ideal material for non-lube or mini-lube service, it can be used in operating temperatures of up to 300°F. For higher operating temperatures, Chinook’s Grade 1616 high temperature material is recommended.

Spring Buttons:
Our spring buttons are designed to prevent direct spring contact with the discs. The buttons guide the spring, preventing deflection and breakage.

Springs:
All Chinook Special Service springs are made of Type 316 stainless steel, inconel or hastelloy. Available in standard spring rate progressions, Chinook will engineer spring sizes to match your plant production characteristics.

Reconditioning:
Chinook has the largest inventory of compressor valve parts in Canada, ready for immediate delivery. We can re-engineer and re-manufacture your compressor valves with attention to plant operating conditions to provide optimum flow and service life. Free pick-up and delivery of overhaul sets are available.
