Gv. internal - external, 2" FM

Product detailed description

This ball valve is commonly used in residential and commercial buildings for control and isolation in water supply and heating systems. Installers typically encounter these valves in domestic plumbing applications, industrial process systems and municipal water distribution networks. The design allows for reliable shut-off with minimal pressure loss due to the full-flow bore configuration. The extended thread length provides additional clearance for installation in tight spaces.

The nickel-plated brass body offers corrosion resistance while maintaining compliance with drinking water regulations. The double-sided lever handle enables operation from either side of the pipe, which is particularly useful in confined installation areas. The valve can be integrated into both new installations and system retrofits requiring reliable shut-off capability under varying temperature conditions.

Technical parameters

Material	Nickel-plated brass CW617N ATEST for potable water
Operating temperature	-20 °C
Nominal pressure	PN 16
Weight	1.81 kg
Code	80004200
Brand	IVAR

The PN16 rating indicates the valve is suitable for systems operating up to 16 bar pressure. The temperature range from -20°C to +120°C allows for use in both cold water supply lines and heated systems. These parameters are essential when selecting components for system pressure and temperature conditions.

Installation and connection

Begin by ensuring the pipeline is depressurized and drained. Clean the male and female threads thoroughly before applying pipe sealing compound or PTFE tape. The 2 inch FM connections require standard pipe wrenches for tightening. Verify correct alignment between the valve and pipe to prevent stress on the joint. Common mistakes include over-tightening, which can damage the sealing surfaces, and using incorrect thread sealants incompatible with the material.

Compatibility and accessories

This valve is designed to work with standard threaded piping systems. For complete system integration, ensure compatible pipe fittings and gaskets are available. When installing multiple units, consider ordering in bulk quantities to maintain consistent performance across the system.

Technical background for designers

The ball valve operates via a rotating spherical disc with a through-hole aligned with the flow path. The nickel-plated brass CW617N material provides good mechanical strength and resistance to corrosion in water environments. The full-bore design minimizes flow restriction, making it suitable for applications where pressure drop is critical. Long-term performance depends on proper installation and avoiding excessive torque during operation.

Service and operation

Regular inspection should focus on checking for leaks around the threads and verifying smooth lever movement. The valve requires no scheduled maintenance beyond visual inspections during routine system checks. Ensure the system is depressurized before attempting any maintenance work.

Frequently asked questions
