Valves control gas and liquid flow in almost every process and system. There are many variables to be taken into consideration when choosing a valve for aggressive medium. This will ensure the valve is compatible with the operation’s system design.
Here are some plastic valves that are suitable for aggressive medium:
Pressure relief valve limits the static pressure to a constant and maximal settled value by opening the outlet (to the discharge line) when the pressure is overriding. An EPDM diaphragm, PTFE coated, separates the mechanical parts body and the channel.
- Body parts in PPH
- All wetted parts in plastic
- Protection of pumps and process lines
- PTFE coated diaphragm
- Adjustable from 0.5 to 10 bar
- From DN 10 to DN 25
Pressure reducing valves reduce in-line pressure at the outlet down to the pre-set value , to adjust on site. Outlet pressure is not directly proportional to inlet pressure.
- Body Material : PVC, PP or PVDF
- Diaphragm: in EPDM with PTFE coat
- Gauge 0-10 bar, with built-in gauge guard
- V182: Spigot ends from ND 10 up to ND 50
- V82 : Spigot ends from ND 65 up to ND 100
A ball valve is a device with a spherical closure unit that provides on/off control of flow. 2-way: allows flow to travel linearly from the inlet to the exit 3-way: allows for flow to travel in multiple directions.
VP Series
- Pneumatic actuator
- Single or double acting, position index
- Status NC or NO
- Material: PPH / PVDF / PVC
- Options: Limit switches box / Pilot valve
VE Series
- Electric actuator
- Position index

A butterfly valve is a rotary motion valve that is used to stop, regulate, and start fluid flow. A 90° rotation of the handle provides a complete closure or opening of the valve.
