The original Chemtrol® True Union design allows the valve and operational components to be conveniently lifted from the piping system for repair or replacement. Tru-Bloc® advances the True Union concept with the self-adjusting energizer O-ring. The valve can be easily joined with the flanged end connections. Please refer to Chemtrol technical data sheets, chemical resistance guides and catalogs for engineering and installation information. PVC Schedule 80 exhibits excellent corrosion resistance properties and has the highest long-term hydrostatic strength of any other major thermoplastic material used for piping systems. Chemtrol PVC valves are lightweight, easy to install, maintenance-free, and will not rust, scale, pit or corrode. Choose Chemtrol® valves for the most reliable, versatile and economical valve option in commercial and industrial applications. Chemtrol® valves are backed by a 1-year limited warranty. Because Chemtrol® is a NIBCO brand the flow-control valves are unsurpassed in quality, performance and longevity.

Nibco MA612AF – Frequently Asked Questions

1) Will the Nibco F45TB-E flanged ball valve bolt up to my existing ANSI 150 flanges?
Yes. The F45TB-E has flanged end connections drilled to match ANSI B16.5 Class 150 bolt patterns, so it mates with standard Class 150 companion flanges in steel or plastic. Bolts, nuts and gaskets are not part of the valve itself, so plan on supplying those plus a full-face gasket suited to your media.
2) Can I run compressed air through this PVC ball valve?
No. The F45TB-E must not be used or pressure tested with compressed air or any other gas. PVC under gas pressure stores energy and can fail explosively. Hydrostatic test with water only. It is rated 150 psi at 73F on non-shock water service, with a maximum service temperature of 140F.
3) Is EPDM the right seal choice, or should I be looking at Viton?
The F45TB-E ships with EPDM O-rings and EPDM seats. EPDM handles water, dilute acids and bases, and most water treatment chemistry well, but it swells badly in petroleum oils and hydrocarbons. If your line carries oils or solvents, EPDM is the wrong elastomer and you want a fluoroelastomer seal version instead. Nibco publishes a plastics incompatibility warning covering polyol ester oils specifically.
4) Is this valve approved for potable water?
The F45TB-E carries NSF/ANSI Standard 14 and NSF/ANSI/CAN 61 listings and is certified to ASTM F1970. It is catalogued as a lead-free application valve. That covers potable water service along with commercial plumbing, industrial and irrigation use.
5) What pipe sizes does the Chemtrol F45TB-E true union ball valve come in?
Three sizes: 3 inch, 4 inch and 6 inch. All are PVC Schedule 80 with flanged ends and an EPDM seal package. The 3 inch is MPN MA612AF, the 4 inch MA612AH, and the 6 inch MA612AK.
6) Does the pressure rating drop as the water gets warmer?
The 150 psi rating on the F45TB-E is stated at 73F. Service temperature is capped at 140F, and PVC loses working pressure capability as it heats toward that ceiling, so a line running hot should not be sized against the full 150 psi figure. For anything above 140F this is the wrong valve material entirely.
7) Can I service this valve without cutting the pipe out?
That is the point of the true union body. The Chemtrol design lets you back off the union nuts and lift the valve and its working parts out of the line for repair or replacement while the flanges stay bolted in place. The Tru-Bloc version adds a self-adjusting energizer O-ring, so seal takeup does not depend on how tight someone cranked the nuts.
8) Is this a full port valve, or will it restrict flow on a 4 inch line?
Full port. The bore matches the nominal pipe size, so a 4 inch F45TB-E passes 4 inch flow with minimal pressure drop. That matters on irrigation mains and low-head industrial lines where you cannot spare the loss a reduced-port valve costs you.
9) Will PVC hold up in a corrosive chemical feed line better than metal?
PVC Schedule 80 resists corrosion well and will not rust, scale, pit or corrode, which is why it gets specified over metal on chemical feed and water treatment piping. It also has the highest long-term hydrostatic strength of the major thermoplastics used for piping. Chemical compatibility still has to be checked against the specific media, and the EPDM seals are the limiting element, not the body.
10) Should I use the flanged version or a socket/threaded true union valve?
Flanged ends make sense when the valve sits at a piece of equipment, a pump, or a tie-in point you expect to break apart, and when the adjoining pipe is already flanged to ANSI Class 150. The tradeoff is bulk, bolt count and gasket cost. If the valve is buried mid-run in solvent-welded Schedule 80 PVC, a socket-end true union valve installs faster and takes up far less space. The true union body means either style can still be pulled for service.
11) What does the valve look like installed, and how do I spot the EPDM version in the field?
Dark grey Schedule 80 PVC body with an orange handle. Nibco uses the orange handle across the Chemtrol true union line, so handle color alone will not tell you the seal material. Match the MPN stamped on the body, MA612AF, MA612AH or MA612AK for the 3, 4 and 6 inch EPDM flanged valves.
