  anodized aluminum ISLT** (locking device) handles and
  pneumatically actuated

2. Needle Valves

Needle valves are typically used in a severe environments, high pressure
sampling systems, high pressure shut-down systems and test stands.

Example features, Screwed Bonnet Needle Valves, H-99 Series:

  disassembling is required

3. Plug Valves

The PLV series offers a manually operated plug valve that
features tight shut-off with high pressure throttling capability,
long life cycle service and low operating torque.
The plug valve is rated to 3000 psig making it an optimal choice
for variety of instrumentation systems such as sampling,
analytical purging and cleaning applications.

PLV Features:

• Tight shutoff with throttling capability
• One piece body design
• Replaceable plug assembly
• Stainless Steel and Brass construction
• MAWP* 3000 psi (206 bar)
• MAWT* 400ºF (204ºC)
• Variable end connection types and sizes from 1/8” to 1/2” (6mm to 12mm)
• Colored Nylon handles
• Low operating torque
• Easy to maintain and clean
• Choice of O-rings for chemical compatibility
• Passivated Body

4. Toggle Valves

The H-1200 Series standard toggle valve is a compact design for normally closed
and quick on/off service. Moving the handle 90 degrees upwards opens the valve
to full flow and stops it firmly in the open position. Shifting the handle position
downwards shuts off the valve by spring return. The PTFE soft seat at the tip of
the stem provides a positive repetitive seal.

H-1200 Features:

• Compact rugged design
• Stainless Steel and Brass Construction
• Panel mountable
• Quick On/Off service
• Straight and angle patterns available
• Sizes: 1/8″ & 1/4″
• LET-LOK , male and female NPT ends
• MAWP 300 psig at 20°C (70°F)
• Temperature rating: -20°F to 200°F (-28°C to 93°C)
• Flow coefficient (Cv) 0.11 to 0.2
• Colored Nylon Handles

5. Metering Valves

The H-1300 Series is a moderate-pressure instrumentation
flow-regulating needle valve. It is generally used for
instrumentation panels, sampling systems and accurate
applications.
The valves are compact in size and structure and offer reliable
low and moderate flow regulation with long service life.

H, HF & HXF-1300 Series Features:

• Forged-body 316 St.St.or Brass Construction
• Straight and Angle Patterns and Panel Mounting
• MAWP 2000 psig – (138 bar) For HXF
• MAWP 1000 psig – (69 bar) For H, HF
• MAWT 400°F (204°C)
• Flow coefficients (Cv) from 0.004 to 0.15
• Round & Slotted Handles with Screwdriver Slots
• HAM-LET LET-LOK® Ends, Male & Female
  NPT, HTC® Face Seal Bead End Connections
• 1°, 3° and 5° Stem Taper for required flow control
• Stem with Stopper Shoulder for maximum life

6. Check Valves

The H-400 Series is a compact design for instrumentation panels
and systems, which provides an accurate operating point. H-400
valves are normally closed. When differential pressure between
the inlet and outlet is higher than the set pressure of the spring,
the loaded poppet will move backwards and will enable a free
passage of flow through the valve.

Example Features, H-400 Series:

• 316 St.St. and Brass construction
• Moderate Pressure Characteristics up to 3000 psi (206 bar)
• Compact Design
• Variable fixed cracking-pressure springs
• HAM-LET LET-LOK®, Male & Female NPT, and HTC®
  Face-Seal Bead Ends.

7. Relief Valves

The H-900 series is a relief valve for low pressure service.
The valve is normally closed. It will open when the system pressure
reaches the set level. It will re-close when the system pressure falls
below the set level.

H-900 Features:

• H-900 is available as CE/PED products
• 316 St.St. Construction
• Service 10-225 psi
• One spring for all set pressure range
• Available in all pipe threads and LET-LOK® connectors
• Sizes: 1/4″ or 6mm

8. Excess Flow Valves

How it works:

1. The poppet is loaded by a spring in a normally open position as long as the system is balanced.
2. If the system becomes unbalanced and the downstream pressure drops, the poppet moves
towards the sealing area and prevents free, uncontrolled excess flow from the line.
3. If the downstream pressure increases, the ventilation outlet (“bleeding”) enables the system to
balance the pressures and (with the help of the spring) reset the system. In this situation, the
poppet reverts back to Normally Open.

HP-911 Series Features:

• Stainless Steel Construction
• MAWP 6000 psi (413 bar)
• MAWT 400°F (204°C)
• Variable connection sizes
  (1/8 to 1/2” & 6 to 12mm)
