ZPB-P

Structural and material execution:

The construction of the ZPB-K valve is based on a two-piece structure consisting of a cast iron body and a cap. Inside the body there is a rubber insert called the "diaphragm", which is the sealing element of the valve. The clamping of the diaphragm is achieved by moving two beams working in the body: the lower one up and the upper one down. The movement of the beams is caused by turning the wheel. The valve is closed by turning the wheel clockwise. The ZPA type diaphragm valve consists of a body and a diaphragm,
placed inside the body, which cooperate with each other. The valve is closed by pressing the diaphragm head against the body seat. Ended on both sides with cast iron flanges in accordance with PN-EN 1092-2
As a shut-off and flow control fitting, it can be controlled:
– wheel – manually,
– electric drive, e.g. ZPE, ZPB-E
– pneumatic drive, e.g. ZPR, ZPB-P

Scope of application:

Diaphragm valves can be installed in vertical or horizontal pipelines in any position, and they should operate with laminar flow, which significantly extends the valves' operating time, especially when the medium contains solid abrasive particles.
Nominal pressure: PN6, PN10, PN16
Operating temperature: ZPA: -5°C ÷ + 65°C
ZPB-K: -5°C ÷ +75°C; -5°C ÷ + 110°C
Designs of diaphragm valves for other temperatures require separate arrangements.
Destiny
Diaphragm valves are designed to work as a closing element in installations with media such as:
– cold water,
– hot water,
– acids, lyes
– mineral oils
– highly abrasive media, heavily contaminated media,
mudbloods
Other media after consultation with the manufacturer
