Product catalog summary

Application Area: The KVF Quick-Closing Valve is designed for use in pipe systems for steam and air media across all industrial sectors. It serves as an automatic emergency shutdown device and shut-off valve in piping systems.

Advantages: The valve offers a closing time of less than 1 second, ensuring a high safety level with zero leakage. It is built for heavy-duty use with high operating cycles and a long service life.

Technical Data: The valve is a single-seated straight-through globe valve conforming to DIN/EN standards. It features stem sealing according to TA-Luft with a stainless steel bellow and additional lip seal. The valve includes a maintenance-free guide bushing and a piston actuator with an integrated closing spring. Options include a soft opening function and flow control via a smart positioner.

Operating Data: Suitable for steam and air media, the valve operates at a maximum pressure of 40 bar g and temperatures from 0 to 400 °C. It requires compressed air at 4-8 bar g and operates on control voltages of 230 V, 50 Hz, or 24 V DC. The IP protection class is IP 65, with no restrictions on mounting position or location.

Materials: The valve body is made of A 216 WCB, with a valve seat cladded with 1.4009. Other materials include steel for the plug gasket, 1.4541 for the bellow, and a combination of steel and aluminium for the actuator.

Dimensions and Parameters: The valve is available in sizes DN ½" to 2" with ANSI 300 lbs. The maximum service pressure is 21 bar g at 400 °C, with kvs values ranging from 5 to 46 m3/h. The closing time is less than 1 second.

Accessories: Available accessories include a 4/2-way solenoid valve, limit switches, and a transparent protection cover for limit switches and optical position indication. Other materials and accessories are available upon request.
