Rotary valves
Heavy-duty shut-off and bottom-drain ball valves
The KN series of ball valves features solutions from a modular system. The selection of fluoroplastic linings, the large temperature/pressure spectrum and the numerous options enable a customized solution for nearly every application with highly corrosive and ultrapure media—and does so with largely common parts.
Options:
- Ball valve
- ISO version (KN/F, KNP/F)
- ASME version made of stainless steel (KNA-S/F)
- ASME version (KNA/F, KNAP/F)
- Flangeless compact valve (KK/F, KKP/F)
- Bottom-drain valves (KA-N, KAP-N)
Standard ball valves
The design of the BVI and BVA series is based on Richter's more than 30 years of application experience with lined ball valves. They have an excellent price/performance ratio for use in highly corrosive processes.
Options:
- ISO version (BVI/F, BVIP/F)
- ASME version (BVA/F, BVAP/F)
Control valves
This series provides plant operators with compact control valves that have high control accuracy. In many applications they are a very economical alternative to bellows-sealed globe valves and rotary plug valves.
Options:
- ASME version (KNAR/F, KNARP/F)
- ISO version (KNR/F, KNRP/F)
Globe valves
Diaphragm valves
Richter diaphragm valves are reliable and easy to handle. They are cost-effective and therefore among the most widespread shut-off, control and throttle valves.
Options:
- ISO version (MV/F)
- ASME version (MVM/F)
Bottom-drain valves
Richter bottom-drain valves are hermetically sealed, thanks to a bellows stem seal. They are particularly suited for use with highly aggressive and ultrapure liquids. They are universally resistant to chemicals and more cost-effective than valves made of special metals.
Options:
- Manually operated (BAV/F)
- Remotely operated (BAVM/F)
Sampling valves
Richter sampling valves enable representative and reliable sampling of pure liquids and liquids with a small amount of entrained solids directly from the medium flow.
Options:
- PFA lining (PA/F)
- Stainless steel version (PA/S)
Butterfly valves
Richter butterfly valves stand the test in a wide variety of process technology systems while being cost-effective, compact and easy to replace. Depending on the housing version, the butterfly valves can be installed as wafer, flanged or end-of-line valves.
Options:
- Double-flange housing (NK/F, NKP/F)
- Lug-style housing (NKL/F, NKLP/F; NKL-C/F)
- Intermediate-flange housing (NKS/F, NKSP/F, NKS-C/F)
Control valves
Bellows-sealed control valves
Richter's Chemical Globe Control Valve series RSS/F is ideal when it comes to precise flow control, for example in the chemical, pharmaceutical, and biotechnology industries. Bellows and safety gland seal ensure a hermetic seal that complies with the German Clean Air Act (TA-Luft).
Bellows-sealed shut-off valves
These valves (HV/F, HVR/F) with quick-opening plug are preferred where the required hermetic seal means, for example, that a ball valve or butterfly valve cannot be used. When equipped with an equal-percentage or linear regulating cone, the HVR can also assume a real control function.
Safety valves
Richter's KSE safety valve is certified for steams, gases and liquids. The KSE is bellows-sealed; the seat and cone can be replaced. Richter provides a low-pressure version particularly for chloralkali electrolysis.
Options:
- ISO version (KSE/F, KSE-C/F)
- ASME version (KSEA/F)
Overflow valves
Richter's spring-loaded GU/F overflow valve was designed for safeguarding the pressure of closed pipelines and system components.
Low-pressure valves
The direct-acting overflow valve of the LPV series is designed for use with corrosive and pure liquids, gases and steams. It can be installed on vessels or in pipelines as a respiration and vent valve.
Options:
- Respiration and vent valve (LPV-A/F)
- Straight-way valve (LPV-D/F)
Sight-glass valves
Richter's sight-glass valves enable you to observe the flow, fill level, status, colors and gas contents of media in pipelines and vessels and in the vicinity of pumps.
Options:
- 2-way design (PSG/F)
- 3-way design (TSG/F)
- 2-way cylindrical sight glass (SGS/F)
Strainer
With Richter's GSO strainer design, the strainer basket can be changed from above without directly contacting the media. This eliminates the need to empty the strainer and remove the media as before. Changing the strainer basket removes all impurities.
Check valves
Richter's check valves prevent liquids, gases and steam from flowing back in pipelines. They are installed, for example, to prevent the pump from siphoning or if vessels need to be vented/respirated within approximate setting ranges.
Options:
- With solid ball (BC/F, CV/F)
- With hollow ball (BCV/F, CVV/F)
- Orientation: horizontal (GR/F)
- With integrated sight glass (SR/F)
Drives
Rotary piston drives are the technically and commercially optimum solution for automating Richter ball valves and butterfly valves. They are fully developed and meet the high quality requirements of chemical and industrial process engineering. The interfaces to the fitting or control valves and signaling devices correspond to DIN/EN ISO 5211 or VDI/VDE 3845/NAMUR.
