Under the EPI brand we offer industrial ball valves for water, air and aggressive media. Most series are made of 1.4408 stainless steel with PTFE seals, while the K809 high-pressure valves are made of A350 LF2 carbon steel.
You can choose by connection — female thread, weld ends or flanges — and by design: two-piece, three-piece that can be taken apart, three-way, high-pressure up to 140 bar, and valves with an ISO 5211 flange for a pneumatic or electric actuator.

How to choose an EPI ball valve
1. Connection
For threaded pipe choose a female thread, for welded pipe choose weld ends. Flanged systems need flanged or wafer valves.
2. Pressure
The highest pressure in the system must not exceed the pressure stated for the valve. Above 63 bar, choose the K806 or K809 series.
3. Material
Stainless steel valves suit water, air and aggressive media in chemical and food processing. The carbon steel K809 valves are mainly intended for high pressure.
4. Operation
All valves have a lever. If you want to operate the valve remotely, choose a series with an ISO 5211 flange and add an actuator.
Frequently asked questions
- What does a three-piece valve mean?
- The body consists of three parts bolted together, so the valve can be taken apart, for example for cleaning. Series VL001, K806, K809, VL521T and VL521FAS are three-piece.
- Which EPI valves can take an actuator?
- The series with an ISO 5211 flange: VL321, K806, K809, VL521T, VL851 and VL140F. Ready-made assemblies of these valves with OMAL pneumatic actuators are in the category of valves with pneumatic actuators.
- What is the difference between K806 and K809?
- Both valves are high-pressure, three-piece and come with an EN 10204-3.1 certificate. K806 is made of 1.4408 stainless steel, K809 of A350 LF2 carbon steel.
- What is the antistatic design of VL521FAS?
- The antistatic design to EN 13463-1 conducts static charge from the ball and stem to the valve body. The standard covers equipment for potentially explosive atmospheres.
- How do I know the valve is open?
- On a two-way ball valve the lever shows the flow direction: lever in line with the pipe means open, across the pipe means closed.
