Control Seal - Rising Stem Ball Valves (RSBV) for Extreme Conditions

Control Seal's Rising Stem Ball Valves (RSBV) are engineered to operate reliably under severe conditions where traditional valve designs may falter. These valves feature a unique single-seat non-friction design, ensuring long-lasting performance. With size ranges from 1” to 36” (DN25 to DN900) and pressure capacities of 150# to 2500#, they accommodate a wide range of applications. These valves perform efficiently under high/low temperatures (-196°C to 538°C), high differential pressures, and can handle media containing solid particles. The innovative design includes a friction-free opening and closing mechanism, which minimizes wear, ensuring longevity and minimal leakage. Additionally, the valves offer top-entry access for maintenance without removing the valve from service. Suitable for molecular sieve, LNG dehydration, hydrocracking, and petrochemical processes, these valves are often used as blow-down, shutdown, or emergency shutdown valves. The design adheres to critical standards such as API 6D and ASME B16.34, and supports several actuation options including manual, pneumatic, and electrohydraulic.

Control Seal - Double Block and Bleed Valves for Isolation and Bleeding Applications

The Control Seal Double Block and Bleed Valve (DBBV) is engineered to deliver frictionless, reliable sealing solutions across diverse industrial applications, including metering, tank farms, airports, and pipelines. This valve's design addresses common issues found in traditional valve systems by eliminating friction during operation and requiring no maintenance. Supporting a wide range of pressures (150# ~ 2500#) and temperatures (-196°C ~ 250°C), it accommodates reduced or full bore configurations, with customizable materials and connections. The innovative dual expanding plug mechanism provides 100% bubble-tight sealing independent of line pressure, ensuring that downstream and upstream isolation and bleed functions are efficiently managed. A thermal relief system helps to vent overpressure without compromising pressure balance. The valves are compliant with strict testing standards like API 6D, ISO 10497, and have been fire-safe certified. Easy slip replacement reduces downtime, and the self-locking operating mechanism prevents unintentional closures.

Control Seal - Triple Offset High Performance Butterfly Valves

Control Seal's triple offset butterfly valves are designed to ensure zero leakage through precise engineering. The unique offset angle of the seat and seal results in even seat loading, eliminating wear-inducing friction during operation. These valves cater to various industries, including LNG, hydrocarbon processing, geothermal steam, and more. They are specifically engineered to handle extreme temperatures ranging from -196°C to 820°C and pressures from 150# to 2500#, with customizable connection and material options. The design adheres to rigorous standards such as API 6D and ASME B16.34, ensuring reliability where other valves may fail. Featuring non-rubbing seating surfaces and multiple actuator options—pneumatic, electric, hydraulic, or manual gear—the valves retain their effectiveness and longevity over time. Control Seal emphasizes a solution-oriented approach, tailoring its products to meet distinct project requirements and offering competitive pricing and strong after-sales support.

Axial Flow Valves (AFV)

Control Seal - ON / OFF Axial Flow Valve

Control Seal ON / OFF Axial Flow Valve series is designed for quick operation and tight shut off.

Control Seal - CONTROL Axial Flow Valve

Control Seal's Axial Flow Valves are engineered for high performance in various demanding applications. They offer a versatile range with sizes from 1 inch to 48 inches and pressure ratings from 150# up to 2500#. These valves can operate at temperatures between -196°C and 250°C, catering to both cryogenic and high-temperature applications. The design includes a pressure-balanced piston for rapid operation and minimal torque requirements, minimizing the need for large actuators. Unique features include a streamlined egg-shaped body for reduced noise and turbulence, non-slam operation ensuring bidirectional and bubble-tight sealing, and special trims available for precise flow control and surge relief applications. Made for oil and gas, water management, and severe service conditions, these valves also adhere to rigorous standards like API 6D and ISO 10497 for fire safety. The design elements like the quarter-turn stem and advanced sealing mechanism ensure reliability and performance under extreme conditions.
