Self Draining PV valves
We design all products in order to allow any condensate to drain away from seating areas.
Designed for minimal leakage
Our standard seating design minimises leakage down to less than 1 scfh at 90% of set pressure.
Stainless steel internal Parts
We manufacture the B150’s internal parts in stainless steel as standard but we can supply the valve with non standard materials, if requested.
Specify your connections
3B Controls will supply all valves with full form flanges based on individual requirements. However we can supply alternative connections on request.
Manufacturing for non-standard applications
We can provide a broad range of options to meet particular applications. We can offer non-standard materials like Hastelloy and we can provide a variety of plastics for dealign with highly hazardous environments, as well as going the extra mile and supplying with special coatings. If dealing with low temperature applications, we can coat the internal parts with PTFE to prevent seizure.
