Photo of Control Chemical-Resistant Check Valves

Tubing barbed check valves are constructed of chemical-resistant Kynar® body and Viton® valve for an inert high purity smooth and clear flow path. Use with acids, bases, water, chemical processing, and alcohols. Use for liquids, gases, pressure, and vacuum applications. Operating ranges are 0 to 50 PSI and –40 to 126°C. Autoclavable, zero maintenance, unit installs in any position. Prevents damage to equipment, pumps, and flow systems by preventing backflow.

Relief valves, stainless steel. These valves are same construction as V1000 and V1020 Valves, but are equipped with No. 214 MGM relief mechanism. Prices shown are for pressure settings of 800 psi or below. Setting above 800 psi is available for an additional charge. Relief mechanism settings are in 25 psi intervals. M=Male, F=Female.

Needle Valves with Straight Body. These valves are built for service up to 1,500 lbs., although wall thicknesses are sufficient to withstand much higher pressures. Each valve has a replaceable PTFE tip on the end of the stem and replaceable O-ring packing of synthetic material. The packing is located between the fluid chamber and the thread of the valve stem and bonnet so the thread can be lubricated. Full flow valves have a large hole through the body for fast flow where close control is not necessary. Fine flow valves have a small hole through the body for close control.

Outfitted with a convenient on/off valve for use in dispensing from aspirator bottles. Just squeeze and hold the soft center of the valve to begin flow: release it to suspend flow. Made of silicone rubber and polypropylene, the internal surfaces are coated with a fluorocarbon resin for maximum chemical resistance. Steam autoclavable at 121°C (250°F).
