1” press-down valves

1” PRESS-DOWN VALVES
1” PRESS-DOWN VALVES
Press-down valves with continuous actuation: the pressure
on the stem causes the opening of the actuating system.
They function both in the upright or upside-down position,
according to the characteristics of the valve housing.
Given their versatility and the characteristics of their
component parts, they can be utilized in most of the
products available on the market.

RKRA
CONTINUOUS VALVE
HOUSING
The valve is equipped with a fast filling housing in which gas orifice (VPH) and product orifice (RTP)
can be of various dimensions. The dip tube is mounted outside the housing tang.
RKRA valves are generally employed for water-based products filled with liquid gas (LPG) or for highly
inflammable products. In this case the orifice dimensions selected according to the gaseous or liquid
phase, guarantee a perfect atomization of particles, thus producing a very fine and uniform spray
that reduces the inflammable properties of the product.

HOUSING
The NKR valve, with reduced stroke and spring, is equipped with a housing with two side slots,
that permits the complete emptying of the can in the upside-down position.
The valve does not need a dip tube. Nevertheless, the housing is supplied with a tang
where a dip tube can be inserted in order to facilitate the selection of the valves
in the automatic feeding machine.
NKR valves are generally employed for products that must be actuated in upside-down position,
such as hair mousse, cosmetic creams, food products, road markings paints, etc.
