The cross section drawing below shows the design features and relative position of working parts of the M&H Style 1450 butterfly valve.


Non-Adjustable Bronze O-Ring Cartridge		Stainless Steel Shaft Ruggedly constructed valve shafts of 304 Stainless Steel meet or exceed AWWA Standard C-504.
Bearings Generously sized, low-friction, reinforced Teflon stainless steel backed bearings provided on operator and thrust ends are self-lubricated for valve live...no maintenance is required.
		Valve Body Heavy duty ASTM-A126 Class B Cast Iron body designed and manufactured to meet or exceed AWWA Standard C-504.
Taper Pins For full metal to metal contact, vane to shaft connection is accomplished by stainless steel taper pins secured with stainless steel lock nuts.
		Flow Through Vane Innovative design of Style 1450 flow-through vane provides large free flow area without sacrificing vane strength. Greater flow-through area results in less pressure drop than conventional vanes. Vane construction is of A-536 Ductile Iron to meet or exceed AWWA Standard C-504.
The M&H Style 1450 incorporates a unique sealing system in which the seal is locked into a vane recess and is further restrained by a serrated clamp ring. Seal relaxation when the valve is in the open position is eliminated. You are assured of uninterrupted 360º reliable and mechanically adjustable sealing as well as reduced wear and lower seating torque. Should field adjustment be required, one man with a torque wrench does the job in minutes without valve disassembly. 1-Vane; 2-360º Rubber Seat; 3-Stainless Steel Self-Locking Screw Fastener, with Nylon sealing Sleeve; 4-Stainless Steel Body Seat Ring; 5-Stainless Steel Seat Retaining Ring;6-Valve Body
