Full range for Spitzer BT and Feldbinder Cement/Powder; Kassbohrer 24–72h on order. Replacement includes opening-pressure test on bench and TDT-ready service record. Shipping DE/AT/CH 2–3 working days, EU B2B invoice.
Valves are the components that determine the safe operation of a silo trailer under pressure. A safety valve that does not open at excess pressure — or opens too early — is a hazard for operators and grounds for TDT rejection. A leaking ball valve means cargo loss at the customer’s site.
PHS Magnum stocks valves for the most common silo trailer models. Parts sales with shipping and workshop fitting available at the same address.
Types of silo trailer valves
Safety and pressure relief valves
Safety valves open when the tank’s certified pressure is exceeded (typically 3.0–3.5 bar for aluminium silo trailers, 2.0–2.5 bar for some cement tankers). After several years of operation the opening pressure can drift — valves must be regularly tested or replaced.
In stock:
- Safety valves 1.5 / 2.0 / 2.5 / 3.0 / 3.5 / 4.0 bar
- Fittings: G1/2", G3/4", G1"
- Materials: 316L stainless steel, aluminium
Ball valves
For controlling the flow of bulk material in chambers and discharge fittings. Most common sizes: DN80, DN100, DN125.
In stock:
- Ball valves DN80 / DN100 / DN125
- Seals: PTFE (chemical-resistant, for cement and granules)
- Body materials: aluminium, cast iron, stainless steel
- Actuation: manual (lever), pneumatic actuator
Butterfly valves
For discharge throttle plates and flow control. Typical in Feldbinder KIP and EUT systems.
In stock:
- Butterfly valves DN100 / DN150 / DN200
- Seals: EPDM (standard), PTFE (for aggressive products)
- Construction: aluminium, stainless steel
Regulating and other valves
Pressure equalising valves, breather valves, section valves — on order, typically 24–72 hours.
How to identify the correct valve
When ordering valves, please provide:
- Trailer model (e.g. Spitzer BT 65, Feldbinder EUT)
- Tank serial number (TDT plate)
- Working pressure (for safety valves — from the plate or TDT certificate)
- Thread or flange size (DN, inches)
- Photo of the old valve — often sufficient
In case of doubt, call: +48 604 800 869 — we will help identify the correct part.
Valve service
When valves are fitted at our workshop we carry out:
- Leak test after fitting
- For safety valves: opening pressure verification on test bench
- Service record for TDT documentation
