Chemline Plastics Limited products

The Chemline Type 21 True Union Ball valve incorporates state of the art features for long term performance. This is a full port, full blocking True Union valve pressure rated at 16 bar (230 psi). Double stem o-rings and Safety Shear stem design provide for a high degree of safety on hazardous fluid applications. All sizes have an ISO standard actuator mounting platform integral to the valve body. This provides for sturdy and secure mounting of pneumatic or electric actuators.

Chemline Type 27 Compact Industrial Ball Valves are manufactured to the same high quality standards to the Type 21 True Union ball valve. They are used on applications where union end valves are not necessary or desired such as drain valves for tanks. They are also lower cost and more compact.

The Chemline Type 23 Multi Port Ball Valve incorporates all the quality features of the Type 21 True Union type. One Multi Port valve eliminates the need for two standard ball valves and a tee in many cases.A choice of several flow patterns is available. L-Port is supplied standard. X-Port offers flow straight through ports 1 and 2. T-Port connects all three ports simultaneously.

Chemline SL Series Cavity Free Ball Valves are molded-in-place full port 1/2” to 2”, available in PVC and PP with a polyethylene ball.

Chemline SM2 Series Metering Ball Valve is designed for fine linear flow control of chemicals or clean fluids. The ball is solid with graduated V-groove cut on the outside surface. Precise linear flow control is accomplished through 180 degree rotation of the handle. With a positioning electric actuator, this becomes an inexpensive control valve. If higher Cv values are required, refer to SP Series Proportional ball valves.

Chemline elastomer seated butterfly valves have a successful history of over 40 years and have replaced metal valves in many difficult process applications. Type 57P body, disc and seat are designed to offer excellent flow characteristics and low closing torques. Stem torques are unaffected by excessive flange bolt torques. Valves up to 16” have corrosion resistant FRP gear operators. Top flange and shaft dimensions are to ISO 5211 standard for easy mounting of actuators. A large selection of body, disc and seat materials permit these valves into a wide range of on/off and throttling control applications in lines up to 24” sizes.

ChemValve Type CST-K fluoropolymer lined butterfly valves feature a composite thermoset plastic body and TFM seat. These valves are designed for zero leakage in the toughest of corrosive applications up to 130°C (265°F) at 150 psi. TFM is a superior grade of PTFE. The properties of the high density TFM liner provide superior performance vs. conventional PTFE lined valves. These include lower cold flow (deformation) and less permeation for longer life with aggressive chemicals. The one-piece shaft/disc is overmoulded with PFA which is a high density material also. The vinyl ester body reinforced with carbon and glass fibres is essentially indestructible and has outstanding external corrosion resistance.

Chemline PVDF Damper Butterflies have performed successfully for many years in the most demanding process control applications. With the PVDF disc and PVDF body and titanium shaft and no elastomer these valves are excellent in high temperature and abrasive applications. The precision machined disc allows for Class III leakage rates (as per ASTM B16.104 [1976]) for valves from 4" to 24" and Class II for the rest. Available from 1-½" to 24" sizes they can be used for a wide range of throttling applications.

Chemline Type 14(1/2” to 4”) and Type 15(5” and 6”) Diaphragm Valves are an improved version of the older DV Series. The 8” and 10” DV’s are still current design but are now called Type 72. Types 14 and 15 have been redesigned using modern computer design technology. Improvements are higher pressure resistance, lower hand wheel torques to close, better hydraulics (lower pressure losses) and other features. Tests show Type 14 to outperform major competitors in resistance to bonnet leakage on tough applications with thermal cycling.

The economical and versatile Chemline Ball Check Valve is the most popular type of non-return valves for pipe sizes under 6”. A wide selection of body and seat materials, and end connections are available for many different applications. It has good flow capacity and will handle many slurry and suspended solid services. This valve works in both horizontal and vertical lines. The Foot Valve is for end of line services such as sumps.
