Toggle Valves<br />
Ball Valves<br />
Toggle valves are designed<br />
primarily as on-off valves for<br />
low pressure applications (less<br />
than 250 psig). The handle<br />
position provides a quick<br />
verification of the on/off<br />
status.<br />
5228<br />
Ball valves are designed<br />
to throttle or shut off liquid<br />
and gas lines in high pressure<br />
applications (1500-2500psig).<br />
They are available in 2-way or<br />
3-way configurations.<br />
5230<br />
Plug Valves<br />
Plug valves are designed<br />
to throttle or shut off liquid<br />
and gas lines in intermediate<br />
pressure applications (less<br />
than 500 psig). They generally<br />
have a higher temperature<br />
limit than ball or toggle<br />
valves.<br />

Metering Valves<br />
Metering valves are multiturn<br />
valves designed to<br />
regulate gas flow.<br />

Parker Toggle Valves<br />
These forged-body valves are<br />
positive, soft-seat shut-off valves<br />
designed for quick opening and<br />
closing. Shut-off force is constant<br />
because of the spring load. The<br />
handle locks in the open or closed<br />
position. A TFE stem tip provides<br />
a leak-tight seal. The maximum<br />
working pressure is 250psig;<br />
Part No. 2328<br />
maximum temperature is 93°C.<br />
They are made of brass or 316 stainless steel with TFE<br />
seat, Viton ® packing and nylon handle. All other parts<br />
are 316 stainless steel.<br />
Hoke Toggle Valves<br />
These valves feature a simple,<br />
reliable, low-maintenance design<br />
that is well suited for a wide<br />
variety of applications. They<br />
are made of brass or stainless<br />
steel and include long-lasting<br />
Viton ® seat and o-ring packing<br />
for positive pressure or vacuum<br />
applications. The maximum<br />
operating pressure is 200psig<br />
and the maximum operating<br />
temperature is 149°C.<br />
