Description
ABZ Valve® Butterfly Valve, Double Offset Lug Style, Series: Elite 400, 3 in Nominal, 150 lb, 5.51 in Top to Inlet Center, 316 Stainless Steel Body, 316 Stainless Steel Disc, Stem & Pin Material: 17-4PH Stainless Steel (Stem)/316 Stainless Steel (Pin), Softgoods Material: PTFE, 10.79 in H
Features:
- Underneath drawn gland packing - Allows for ease of user adjustment to the gland nuts and direct mounting of actuation
- Stem retention system - Provides positive stem retention above the packing
- Mounting flange - Designed to direct mount actuation for ease of installation and cost savings, no bracket is needed for manual actuation or for automatic automation up to 20 in
- Packing - PTFE is a cup and cone system, graphite is die-formed rings for positive seals
- Bearings - Made of 316 stainless steel sleeves impregnated with RTFE to ensure long service life
- Seat retainer - Heavy duty retainer plate and cap screws provide a full rated bi-directional dead end service valve and the seat retainer seal prevents leakage to the atmosphere past the retainer plate and body
- Seat - Utilizes a solid soft seat with a unique channel design
- This advanced design provides a bi-directional interference and pressure-assisted seal
- This achieves maximum seal at low or high pressures while preventing the seat from bending or deflecting downstream
- Disc taper pins - Pins are offset from the center of the stem, which places them in compression rather than in sheer, this gives them a yield point greater than the stem itself
- Pins are welded in place after final assembly and testing
- Integrally cast disc position stop - Machined position stop in the body locates the disc in the seat to achieve maximum seat and seal life
- Disk - Cast from 316 stainless steel (CF8M - A351) and engineered to allow for quick release from the seat
- The disc has a heavy duty low cavitation cross section connection to the stem
- Stem - Manufactured of high strength 17-4 PH stainless steel to provide maximum strength and stability for high torque applications
- High performance
- PTFE packing
