1/2" valve with flowmeter 0.5-5 l/min
Availability: in stock
Short description
The valve with a 1/2" thread with a flow meter of 0.5-5 l/min is used in heating systems for visualization and manual adjustment of the coolant flow in each of the heating circuits.
The flow meter (valve) 0.5-5 l/min is used in heating systems for visualization and regulation of the coolant flow in each of the heating circuits.
The flowmeter consists of a brass body (3) which is screwed into the supply manifold bar (1) and sealed with an O-ring (13).
A hollow plastic adjusting body (4) is screwed inside the brass body, along which a plastic rod (5) spring-loaded by a stainless spring (6) moves with a stop at the bottom. The plastic adjusting body ( 4) is a tube with an adjusting nut in the upper part and slots (18) in the middle to pass the working fluid through the flowmeter. The hole in the center of the adjusting body ( 4) of the flow meter is conical, while the diameter in the upper part before the slots (18) is significantly smaller than in the lower part (after the slots). Thus, the stop of the rod (5) is deprived of the ability to move above the slots for the passage of the working fluid. In the lower part of the adjusting body (4), the hole has the form of a cone and expands towards the bottom. A flow indicator (7) is pressed onto the upper end of the rod, against which a stainless spring (6) rests. When the adjusting nut of the housing (4) is rotated, the flow of the coolant from the supply manifold increases / decreases through the slots (18) in the lower part of the brass housing (3) into the adapter nipple (2) and further into the heating circuit. When the section of the slots (18) changes, the flow changes, which drags the plastic rod (5) with the stop, and thus the flow indicator (7) moves with it. By the position of the flow indicator (7) relative to the scale with a range of 0 to 5 l/min, printed on a transparent flask (8), the intensity of the coolant flow through this flow meter is determined. When the section of the window (18) decreases, the rod (5) returns to its original position under the influence of the spring (6). After completing the circuit adjustment, a protective cap (10) is put on the adjusting nut to protect it from damage. Positions 9, 11, 12, 13, 14, 15, 16 and 17 - sealing parts (rings), which are made of synthetic elastomer (EPDM).
