Self-Operated Low-Pressure Relief Valve

GKV-225V port (V-ball type) rotary control valve combines the advantages of zero leakage Class VI bubble sealed ball valves with the high adjustability of control valves, making it suitable for various control valve applications and achieving excellent flow control, lower pressure drop, and fast response.  All V-ball control valves comply with multiple industry standards and certifications, including API 607, ATEX, NACE MR0175, PED, and SIL, ensuring reliability and compliance with international standards.

The GKV1800C Pneumatic single seat regulating valve is a high-precision process control valve that drives the linear displacement of the valve core through a pneumatic actuator, accurately adjusting the flow rate, pressure or temperature of the medium in the pipeline. Its single seat valve body structure (single sealing surface) design, combined with top guide or cage guide system, ensures stability and sealing under high pressure differential conditions, adapts to the continuous regulation requirements of harsh media such as liquids, gases, and steam, and is widely used in automation control systems in industries such as chemical, petroleum, and power, achieving millimeter level control of process parameters.

The GKV16N GKV18C GKV16H series intelligent electric control valve integrates high-precision electric actuators and intelligent control modules, adopts hardened sealing and corrosion-resistant valve bodies, and is widely used in chemical, energy, pharmaceutical and other fields.  

GKV200/220 three-way regulating valve For extremely short on/off cycles in the cooling spray lines of wire rolling mills we developed these three-way on/off control valves. Already for several years they are performing excellently under these severe conditions and guarantee a long life cycle.    

GKSP3000/4000 Self-Operated Pressure Regulating Valve is a spring set direct acting universal pressure regulating valve. It can be widely applied to various low corrosive gases and low viscosity liquids. Choosing the corresponding configuration can achieve upstream pressure control and downstream pressure control. The minimum control pressure is 3KPa, the maximum control pressure is 3600 KPa, the minimum operating temperature is -48 ℃, and the maximum operating temperature is 300 ℃.

GKSP429 Internal Setting Self-Operated Micro Pressure Regulator is a spring set direct acting micro pressure regulating valve that can throttle and reduce pressure of high pressure gas to extremely low pressure, and is only used for post valve control. Suitable for micro pressure control of various gases, especially for micro pressure nitrogen sealing systems. The minimum control pressure is 0.3KPa, the maximum control pressure is 15KPa, the minimum operating temperature is -48 ℃, and the maximum operating temperature is 120 ℃.

GKSP6000 Self-Operated Low-Pressure Relief Valve is a Spring-setting direct-operated universal pressure regulator. It can be use for upstream and downstream pressure control. The lowest control pressure is 5KPa and the highest control pressure is 120 KPa. The lowest operating temperature is -35℃ and the highest operating temperature is 120℃.   High Sensitivity: Low spring stiffness and specially designed diaphragm ensure precise pressure control and fast response. Overpressure Protection: Actuators are equipped with safety mechanisms to withstand very high pressures, enhancing reliability. Low Differential Pressure Operation: Pilot-operated design requires only 1.5 psi inlet pressure differential to open, allowing stable operation even under minimal pressure drop conditions.  

The GEKO Angular Control Valves of the series GKV3500 (PN 16 - 250) and GKV3800 (PN 16 - 400) are part of the well proven GEKO valve modular parts system. In case of difficult working conditions and sonic relevant applications it is often recommended to use angular valves, because the flow of the medium is turned only once by 90°, contrary to single or double seated valves.
