Pneumatic Fittings

Hand-Operated Valve Fittings

Hand-operated valve fittings open and close local air lines with a lever or sliding control. Tube and threaded versions provide shutoff points at machines, benches and individual pneumatic circuits.

Product features

Hand valves turn the compressed-air supply to pneumatic devices on and off.
Closing a three-way valve stops the supply and vents residual pressure from the downstream device.
Two-way valves stop the supply without venting residual pressure.
The range includes several connection and operating forms for local air-line shutoff.

Construction and materials

Operating knob: POM
Stem guide: POM
Valve stem: POM
O-rings: NBR
Resin body: Engineering plastic
Back ring: POM
Collar: Zinc alloy
Release sleeve: POM
Locking claws: Stainless steel
Tube seal: NBR
Valve seal: NBR
Spring seat: Nickel-plated brass
Spring: Stainless steel
Metal body: Nickel-plated brass
Tubing shown: Nylon or polyurethane

Technical specifications

Fluid: Air only; no other gases or liquids
Operating pressure: 0–0.9 MPa
Negative pressure: −750 mmHg
Operating temperature: 0–60 °C
Compatible tubing: Polyurethane and nylon

The three-way valve exhausts the downstream side when the inlet supply is shut off, supporting maintenance and adjustment of connected equipment.

Two-way valves retain downstream pressure and suit tanks or other devices where automatic venting is not required.

Ordering code

HVFF06-06B

HVFFSeries: HVFF tube-to-tube hand valve.
06-06Tube outside diameters: 6 mm tube connections at both ends in this example.
BValve function: Two-way operation; omit B for three-way operation.

HVFF and HVSF valve function suffixes

Suffix	Valve function	Closed-position operation
B	Two-way	Stops supply without venting downstream pressure
Blank	Three-way	Stops supply and vents downstream pressure

Three-way hand valve in the closed position with downstream exhaust

For a two-way HVFF or HVSF valve, add B after the model code.
