CALORPLAST Heat Exchangers
Custom-designed CALORPLAST heat exchangers are designed for heating or cooling in highly corrosive applications. The product line includes immersion, shell-andtube, tube-plate, gas-liquid, and flexible heat exchangers. Materials of construction include polyvinylidene fluoride (PVDF), polyethylene and polypropylene. The heattransfer media can be saturated steam or hot water up to 35 psig at 281°F, or chilled water or water/glycol solutions.

Type 546 ball valve
A unique ball design creates a gradual change in flow direction, unlike the sudden change typical with traditional ball-valve styles. With each turn, the flow increases or decreases linearly, rather than exponentially, which provides better control. The new ball design, available as an option of the new Type 546 ball valve, features all-plastic construction, with material choices that include polyvinyl chloride (PVC), chlorinated PVC, polypropylene and polyvinylidene fluoride. Manual and actuated versions are available in sizes from 1/2-in. to 2-in.

Schedule 80 PolyVinyl Chloride (PVC) and Chlorinated Polyvinyl Chloride (CPVC) Pressure Piping
This line of Schedule 80 polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) pressure piping has been expanded to include 20-ft lengths of largediameter — 10-in. and 12-in. pipe. Fittings are supplied in a combination of fabricated and molded styles that include a wide range of couplings, bends, wyes, pipe increasers, reducing wyes, expansion joints, brass inert fittings and saddles.The PVC and CPVC systems are resistant to acids, alkalis, alcohols and other corrosives, and they will not rust, scale or pit. The PVC has a temperature rating up to 140°F, the CPVC to 210°F. Their light weight makes installation faster, easier, and less expensive than steel alloy or lined steel.

Type 375 true union ball valve
The Type 375 true union ball valve features an ergonomically designed grooved handle and notched union nut that make for easy gripping during installation and use. Its floating ball design provides leakproof closure, and the full cross-section results in minimal pressure loss. Available in polyvinyl chloride (PVC), chlorinated PVC (CPVC) and natural polypropylene (PP-n), the valve exhibits excellent chemical and corrosion resistance, and is pressure-rated to 225 psi at 73°F. The PVC/CPVC models range in size from 3/8 in. to 6 in. with threaded and socket end connectors (1/2–2 in.), and the PPn sizes are 20 mm to 90 mm (metric socket) with 1/2–2-in. NPT connections. In PVC, the valve meets 12454-B per ASTM D 1784 standards; in CPVC, it meets 233447B per ASTM D 1784.
