SV-700 Series diaphragm valves
are designed for use in plastic
systems ranging in size from
15 to 50 mm (1⁄2 to 2"). The 2-way
PVC or PVDF body and seal
combination can handle ultra-pure,
aggressive, viscous, or abrasive
fluids. Threaded, solvent, or fusion
joint end connectors link to the
bodies. The glandless design of
these valves makes them ideal for
water treatment, reverse osmosis,
ion exchange systems, or
ultra-pure process plant applications.
Remote control allows for use in
hazardous areas.

The valves are operated by
connecting an external pilot fluid to
the piston actuator. The diaphragm

between the actuator and the body
isolates the fluid from the actuator.
The valves do not require
maintenance, and they can be
fitted with optional accessories
for position indication or stroke
limitation. The actuators provide
long service life and air
consumption, and they come in
various sizes.

The convenient location of the
pilot-air connection and the unit’s
compact dimensions allow space­saving side-by-side installation. The

pilot port has stainless steel inserts;
3-way pilot solenoid valves can be
directly mounted. For safety, spring
pressure is relieved when removing
the cover to change the circuit
function or install options.

The body is designed to handle high
flow. Flow direction can be adjusted
as the application requires. A high­quality diaphragm isolates the body
from the actuator and provides the
total external and internal seal
integrity. The valves have no dead
volume and can be installed for
self-draining.
