The Effast BT is a PVC-U 3-way ball valve offering L-type and T-type ball core configurations for flow diversion, mixing, and distribution in water treatment, swimming pool, and light chemical handling applications. Available in DN15 to DN50 with multiple connection options including solvent weld sockets, BSPP/ISO threaded ports, and flanged ends.

When should you choose L-type vs T-type ball core?

An L-type ball core connects two of the three ports at a time, switching flow direction between channels. This is ideal for diverting flow from one source to either of two destinations. A T-type core can connect all three ports simultaneously or any two, enabling both flow mixing and splitting operations in a single valve body.

What are the advantages of PVC-U construction?

PVC-U provides excellent resistance to acids, alkalis, and salt solutions at a fraction of the cost of stainless steel. Its smooth internal surface minimises scaling and pressure loss, while the absence of plasticizers ensures dimensional stability and long service life. Combined with EPDM or FKM seals, the BT handles a broad range of water treatment and chemical distribution duties at up to 16 bar.
