Walk into the back of the wash bay and there's a wall of green metal drawers. The fourth one down, second column from the right, is the valve drawer. It contains every discharge-valve variant we've seen on a tote in the last decade plus the gaskets that go with them. This is a reference piece for anyone who's tried to match a valve and gotten stuck.
The nine valve bodies we keep in stock
- 2-inch buttress to camlock, polypropylene — most common, fits 85% of modern totes.
- 2-inch buttress to Male NPT, polypropylene.
- 2-inch ball valve with camlock out, PVC.
- 2-inch butterfly, EPDM seat, stainless handle.
- 3-inch buttress to camlock, polypropylene (mostly for 330s).
- 1.5-inch buttress to Male NPT, for smaller totes and older Mauser units.
- Vented 2-inch fill cap with 3/4-inch breather.
- Desiccant-vented 2-inch cap (for DEF and hygroscopic liquids).
- 2-inch quick-disconnect (Dixon-style) for pharmaceutical customers.
Gaskets — the part nobody thinks about until it leaks
A valve body lasts decades. The gasket between it and the tote's discharge flange is a consumable. We stock EPDM in three durometers, Viton for chemical-aggressive applications, PTFE for the small percentage of customers who need chemical inertness at temperature, and silicone for food-grade applications where EPDM is forbidden.
The brass problem
We don't stock any brass fittings for tote service. Brass leaches copper and zinc into DEF, into food products, and into any aqueous storage with a pH drift. The marginal cost savings of a brass ball valve is not worth the call-back rate. We had a year of brass-fitting experiments in 2012-2013 and then stopped. Every brass fitting in the yard today exists only on trucks, not on totes.
The valve drawer is the quiet answer to half the “can you help me match this part” emails we get. The answer is almost always yes.
What isn't in the drawer
Cam locks in weird sizes. Anything in aluminum above 3 inches. Old Schütz-specific flange adapters that stopped being made in 2009 — those we have to source from specialty parts houses on request. If you have a Schütz tote from the early 2000s with a flange we don't have in stock, tell us the serial number and we'll dig.
