Flow Control Valves<br />

Parker Toggle Valves<br />

These forged-body valves are positive, soft-seat<br />

shut-off valves designed for quick opening and<br />

closing. Shut-off force is constant because of<br />

the spring load. The handle locks in the open Part No. 2328<br />

or closed position. A TFE stem tip provides a<br />

leak-tight seal. The maximum working pressure is 250psig;<br />

maximum temperature is 93°C. They are made of brass or<br />

316 stainless steel with TFE seat, fluoroelastomer polymer<br />

packing and nylon handle. All other parts are 316 stainless<br />

steel.<br />
