Flowserve Navaltrim control valves are designed for control of liquid flows in heating, cooling and air conditioning systems. Flowserve Navaltrim control valves can also be used as shut-off valves.

Flowserve Navaltrim is a control valve where two cross linked specially designed trim plates decrease the turbulence of the flow to improve the measuring accuracy and practically eliminate the cavitation and noise. This construction is used in sizes from DN40 up to DN300. The valve has an all welded body and is fitted with reinforced Teflon seals which are durable even if the valve is frequently operated and is resistant to impurities and chemicals. The polished stainless steel ball is easy to turn and is designed to provide many years of reliable service. The blow-out proof stem is sealed with 2 O-rings. In smaller sizes the upper one can be changed and in sizes DN65-300 both can be changed. The valve is equipped with fittings for measuring of pressure difference.

CHARACTERISTICS:
The new construction provides many benefits. The effective controlling range is wider than before and the kv value in fully open position has increased significantly. The trim plates built inside the ball eliminate effectively the turbulence and cavitation in all control positions. Due to the non-turbulent flow the pressure information at the valve measuring outlets is very accurate. The valve does not need servicing nor lubrication and is easy to install. These features combined guarantee a long and reliable life time with low running costs. The long and circular stem housing makes the valve easy to insulate. The operating lever can be dismantled, turned 180° and reinstalled to a new position.
