• 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.
