The Mac-Weld 3 Valve Direct Mount T Type Manifold with drain/vent for differential pressure instrumentation. The manifold has one equalizer valve, two isolation valves and two drain/vent ports.
• 316L Stainless Steel Body, stem and trim
• 6000 psig @ 1000 F (414 bar @ 380 C)
• PTFE Packing
• Non-rotating trim provides bubble-tight shut-off
• Optional availability: NACE certified wetted parts and graphoil packing
• Flange a-rings and mounting bolts included with manifold
Mac-Weld 3 valve manifolds are economical and convenient for mounting differential pressure transmitters and differential pressure switches. Mac-Weld 3 valve manifolds are available in direct mount and remote mount configurations.
Mac-Weld 3 valve manifolds incorporate high quality needle valves designed to operate at pressures up to 6000 psig with standard PTFE gland packing. The packing is positioned below the stem threads to ensure no contact between system process and the stem threads. The upper gland body is tightened and secured into position by a lock nut. The lower gland body is directly screwed into the component body and secured into place to prevent accidental loosening of the gland body during operation.
Gland Packing Materials
The standard packing and flange o-ring material for all Mac-Weld valves is Polytetrafluoroethylene (PTFE). The maximum operating temperature is 464°F (240°C). Graphoil packing is available for temperatures above 464°F (240°C).
Mac-Weld instrument valve and manifold components are cleaned during the manufacturing process. Upon final assembly and testing each valve manifold undergoes a final cleaning and drying.
The recommended operating pressure for stainless steel 316/ 316L is 6,000 psig (414 barg). The Maximum Allowable Working Pressure: 6,000 psig (414 barg) @ 38°C (1000F).
