Scorpion - 2/"FF IVAR.08016

Product detailed description

Gate valves are essential components in heating and plumbing systems, providing a means to isolate sections of the system for maintenance or repair. The IVAR Scorpion - 2/ FF is commonly used in residential and commercial buildings, including multi-family housing, industrial facilities, and commercial HVAC systems. Installers and service technicians often encounter these valves in domestic hot and cold water systems, as well as in circulation and heating circuits. The valve is designed to provide a tight seal and smooth operation, making it suitable for applications where frequent opening and closing is not required.

Valve selection and installation must account for the system's operating conditions, including pressure and temperature. The Scorpion - 2/ FF is intended for use in systems where the media is clean water and where the operating temperature does not exceed +80 °C. It is not suitable for aggressive media or high-temperature steam applications. Proper installation ensures the valve functions reliably over its service life.

Technical parameters

Material	Brass CW617N
Operating temperature	+80 °C
Nominal pressure	PN 16
Code	I08016200
Brand	IVAR

The operating pressure rating of PN 16 indicates that the valve is suitable for systems with a maximum working pressure of 16 bar. The maximum operating temperature of +80 °C defines the upper limit for the media temperature, beyond which the valve may not function safely. The material, brass CW617N, is a lead-free copper alloy with good mechanical properties and corrosion resistance, making it suitable for potable water applications. These parameters are critical for correct valve sizing and system compatibility.

Installation and connection

The Scorpion - 2/ FF features an internal female thread (FF) for connection to the system piping. The valve must be installed in a fully open position to prevent damage during tightening. The thread size and type must be verified against the system piping to ensure compatibility. A thread sealant or PTFE tape should be applied to the threads before tightening to ensure a leak-free connection. Common installation mistakes include over-tightening the valve, which can damage the sealing surfaces, and installing the valve in a closed position, which can cause stress on the valve body and seating.

Compatibility and accessories

The Scorpion - 2/ FF is compatible with standard copper and steel piping systems that use internal FF threads. It is typically used in conjunction with other gate valves, ball valves, and check valves in the same circuit. When installing, ensure that the system pressure and temperature are within the valve's specifications. No additional accessories are required for basic installation, but in some cases, a union fitting may be used to facilitate future maintenance or replacement.

Technical background for designers

The Scorpion - 2/ FF operates as a gate valve, where a solid disc or wedge is raised or lowered to control flow. The valve is manually operated via a handwheel or lever. The brass CW617N body provides good strength and resistance to corrosion, making it suitable for long-term use in water systems. The valve is designed to be installed in a straight section of pipe to avoid stress on the body. The service life of the valve is influenced by the quality of the installation, the frequency of operation, and the cleanliness of the media. Proper integration into the system ensures minimal pressure drop and reliable operation.

Service and operation

The Scorpion - 2/ FF requires minimal maintenance under normal operating conditions. However, regular inspections should be carried out to check for leaks, corrosion, or signs of wear on the sealing surfaces. If the valve becomes difficult to operate, it may indicate the need for cleaning or lubrication of the stem. No specific service intervals are provided in the technical data, but any issues should be addressed promptly to prevent system downtime.

Frequently asked questions

Can the Scorpion - 2/ FF be used in a hot water system?
Yes, the valve is suitable for hot water systems with a maximum operating temperature of +80 °C. It is not recommended for higher temperatures.

Is the Scorpion - 2/ FF compatible with copper piping?
Yes, the valve can be connected to copper piping using the internal FF thread. Ensure the thread size matches the piping.

Can the Scorpion - 2/ FF be used in a steam system?
No, the valve is not suitable for steam systems. The maximum operating temperature of +80 °C limits its use to water-based applications.

What is the sealing material used in the Scorpion - 2/ FF?
The sealing material is not specified in the technical data. Refer to the manufacturer's technical data sheet for detailed information on sealing materials.
