Check Valves : Swing Check

Chemline Plastics

The SC Series Swing Check Valve is the heaviest duty solid plastic non-return valve available. The strong one piece flanged body is suitable for installation in any type of piping, horizontally or vertically. A large choice of body materials and seals including PVDF and PTFE allow its use in the most aggressive chemical services. Pressure drop is low due to full flow design.


The Chemline PW Series Wafer Check Valve offers high end features at reasonable cost. This wafer check does not require a separate spacer or flange gaskets. The large orifice and full flow design means low pressure drop. Spring assisted disc closure is standard as well as an optical indication of disc open/close position. A selection of body materials and elastomers allow for a wide range of applications.


The Chemline WP Series Wafer Check Valve is a non-return valve ideal for limited space installations. These valves are economical and available for large pipe sizes, 2" to 12" and larger. They are available in two versions - with or without disc springs. The spring adds force for faster, more silent closing.



Globe Valves - GV Series

Chemline Plastics

The Chemline Globe Valve is an economical throttling valve. Its heavy duty design provides for long service life. The in-line globe design causes relatively high pressure drops, however this is a desirable valve due to its economy and reliability.


LC Labcocks

Chemline Plastics

Chemline LC Series Lab Cocks are rugged quarter turn mini ball valves. They are ideal for general use in instrumentation lines, available at a fraction of the cost of comparable stainless steel valves. Other applications include air lines for aquaculture, for venting gas in pipe lines, process sampling and laboratory use.


LA Series Labcocks

Chemline Plastics

Chemline LA Series Labcocks feature PTFE seats, FKM (Viton) o-ring seals and full 1/4 port. All parts are replaceable. The basic valve is male thread by female thread. Included with each valve are adaptors, plug, O-ring. strap and lockout to provide a variety of end connections. An eyelet is provided for easy valve tagging.


Needle Valves

Chemline Plastics

Chemline N Series Needle Valves are designed for fine throttling of corrosive and ultrapure fluids at low flow rates. Because the seal material is PTFE, these valves are suitable for aggressive chemicals where similar valves with elastomer seals will not stand up.
