Quick-Closing Turbine-Valve for Gaseous Media - Type KVH/HT (ANSI 300lbs.)

Product catalog summary

Application Area
The KVH-HT Quick-Closing Turbine-Valve is designed for use in gas turbines within the petroleum, chemical, and gas industries, compliant with API 616. It is also applicable in gas firing systems on steam boilers according to DIN EN12952/12953 and industrial thermoprocessing equipment as per DIN EN 746.

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

Application
This valve functions as an automatic emergency shutdown device in gas pipe systems, particularly in front of gas turbines, and serves as an automatic shut-off valve in piping systems.

Technical Data
The valve is a single-seated straight-through globe valve conforming to ANSI standards, featuring stem sealing according to TA-Luft with an automatic seal set for tightness testing. It includes a maintenance-free guide bushing and a piston actuator with integrated closing springs. The control element is pressure-balanced for higher pressure tolerance.

Certificates
The valve has an EC-Type examination certificate (Module B) according to directive 2014/68/EU, based on DIN EN 13611, DIN EN 161, and DIN EN 16678. It is certified SIL2 / EN 61508.

Operating Data
Suitable for gaseous fuels as per PED 2014/68/EU and other gaseous media, it operates at a maximum pressure of 50 bar g and temperatures ranging from -29 to 225 °C. The control medium is compressed air at 4-10 bar g, with air quality conforming to DIN ISO 8573-1. The control voltage options are 230 V, 50 Hz, or 24 V DC, with a power requirement of 5.3 VA / 3.9 W. It has an IP Protection Class of IP 66 and can be mounted in any position, indoors or outdoors.

Options
The valve can be equipped with an integrated control characteristic for soft opening and can be combined with an electro-pneumatic positioner for selective flow control.

Dimensions and Parameters
The valve dimensions vary with nominal diameters ranging from DN 3" to DN 12", all rated at ANSI Class 300 with a maximum service pressure of 50 bar g. The kvs values range from 114 m3/h to 1460 m3/h, with a closing time of less than 1 second.

Accessories
Available accessories include a quick venting valve, a 3/2-way solenoid valve, limit switches, and a protection cover for limit switches and optical position indication.

Materials
The valve body is made of A 216 WCB, with a valve seat cladded with 1.4551, a PTFE plug gasket, a stem made of 1.4021, and an actuator composed of steel/aluminium. The piston sealing is made of elastomer.
