LUG BODY
BUTTERFLY VALVE
Series 1000L
A Centric Lug Body Butterfly Valve is a compact, cost-effective valve for low-pressure water/air, featuring a disc centered in the bore (centric design) with threaded lugs on the body for easy flanged installation/removal without disturbing piping
1 .STEM BUSHING: STEM Precision double “D” disc to stem connection drives the disc without the need for screws or pins. The close tolerance, double “D” connection that drives the valve disc is an exclusive feature of the Pascal valve. Disassembly of the Pascal stem is just a matter of pulling the stem out of the disc.
2. STEM RETAINING : The stem is retained in the body by means of a unique stainless steel
Spirolox retainig ring, manufactured from stainless steel as standard.
3 . Top plate drilled to fit iso 5211 dimensions. All handles, gear operators and pneumatic actuators are designed to mount directly.
4. STEM BUSHING : An upper stem bushing, retained by a stainless steel ring, is provided to absorb actuator side thrusts and is PTFE as standard.
5. STEM SEAL: Double “U” cup seal design is self-adjusting and gives positive sealing in both directions. Keeps environmental contaminants from entering the stem bore.
6. BODY: One piece wafer or lug style allows for ease of assembly and maintenance.
7. SEAT: Pascal’s Replaceable tongue and
groove seat design provides complete isolation of flowing media from the body. The seat also features a moulded o-ring which eliminates the need of flange gaskets.
8. DISC/STEM: One piece design. The disc edge is spherically machined and hand polished to produce a bubble tight shut off, minimum torque, and longer seat life. For erosion and abrasion
resistance
