Model E3900 ball valve is used for diverting or mixing fluids. The 4-seat design offers additional port arrangements. A greater Cv value is achieved in most sizes. Media trapped in the valve cavity is reduced substantially with additional seats.
Features & Benefits:
- Equipped with 4-seats so either port can be used as an inlet without leakage.
- A single KTM 3-way valve replaces several 2-way valves, saving valuable space and simplifying piping.
- Positive alignment of body.
- Blow-out proof stem.
- More than 50% of stem length is supported by bushing and valve body.
- Packing acts as seal instead of stem support, minimizing stem leaks.
- Stainless steel static grounding device.
- Sphericity tolerance of the balls, ± 0.0008", and a 4 RMS surface finish are unsurpassed.
- Reinforced PTFE bearing and packing rings help reduce friction.
- Automatic cavity pressure relief.
- Positive position indication.
- Meets NACE MR01.75 for sulfide cracking resistance.
- Locking device capable.
