Multiport Diaphragm Valve The most versatile of all diaphragm valves,
On/Off Manual/Pneumatic offering custom manifolds in a variety of end
Flare, S-300, FNPT, Tube connections, actuators and options.
72.5psi
1/4” - 1” Tested at pressure beyond 1,000,000 cycles.
Poppet-style diaphragm allows media to
recirculate on multiple feed lines while valve
remains closed to the point-of-use.
DIV Diverting Valve
Diverting Valve The true diverting valve was developed for three-
On/Off Manual/Pneumatic way distribution with a high purity poppet-style
Flare, S-300, FNPT, Tube diaphragm valve. The small footprint makes the

The straight flow path applies no stress to the
medium. There is almost no influence to the

Adjustable Flow as slurry, it can also be used for DI water. There is
1/4” - 1” Flare, S-300, FNPT no restriction on the flow path, which gives a high
72.5psi CV value and the ability to fully flush.
Excellent Durability
The use of a pinch seal structure provides
superior durability against foreign substances
caught in the flow passage. The tube does not

Needle Valve
• True linear flow
• Panel mount for easy installation
• PTFE diaphragm isolates media from stems
• Straight, horizontal and vertical L available

Regulators & Flow Control
• Precise and accurate control over pressure
via pneumatic control
• Fluctuations in pressure are instantly adjusted
• Flow control for blend processing
• Point-of-use regulation
Pressure Regulator
HPR-L
Pressure Regulator HPR-L series pressure regulators instantly control
Full shut off (fail-close) fluctuations in pressure due to the quick response
Flare, S-300, FNPT, Tube of the valve. The pressure does not spike, even
72.5psi just after the pump turning on. Sophisticated
1/8” - 1” diaphragm design precisely maintains pressure.
Balance out diaphragm pumps prior to reaching
the point of use.
HPRL-M Manual Pressure Regulator
Pressure Regulator HPRL-M series pressure regulators offer the same
Full shut off (fail-close) technology found in the pneumatic version, with
Flare, S-300, FNPT, Tube manual adjustment. They are easy-to-operate and
72.5psi simple to install. Adjust pressure by rotating the
1/4” - 1/2” handle. Once the desired pressure is set, it
automatically controls fluctuations.
Slurry Pressure Regulator
HPR-S
Slurry Pressure Regulator The internal structure prevents clogging and
Flare, S-300, FNPT, Tube cohesion in CMP slurry applications. It is
72.5psi pneumatically-controlled to provide adjustments in
1/4” - 1/2” pressure. In case of failure, the valves shuts off
50 cc/min - 5 LPM flow.
CFV Constant Flow Valve
Constant Flow Valve The CFV incorporates an orifice into the PTFE
Full shut off diaphragm. The simple system design eliminates
Flare, S-300, FNPT, Tube concerns about pressure fluctuations due to pipe
72.5psi 1/4” length and back pressure.
