- Jamesbury VPVL 100 Valv-Power Spring Return (SR6) Fail Close (NC) Pneumatic Actuator with 8.9 ft-lbs at 80psi supply pressure and 9.8 ft-lbs spring return torque. For use with 80psi supply pressure. Jamesbury Part # MA0126194 VPVL100SR6BD
Single-Source Responsibility
Valves, actuators, and accessories are designed to operate as a unit with the highest degree of compatibility.
Valves, actuators, and accessories can be supplied completely assembled to provide unit responsibility from a single source.
Versatility
Modular designs with same body and end caps for double-acting and spring-return. Springs can be added in the field to convert double-acting to spring return or for changes in supply pressure.
Failure direction can be easily reversed from spring to-open or spring-to-close orientation simply by inverting the pistons.
Actuator to valve attachments comply with ISO 5211.
Solenoid valve and accessory attachments comply with NAMUR VDI/VDE 3845.
A wide range of optional accessories and control devices that include limit switches, solenoid valves, and mechanical safety lockouts are available to satisfy virtually all automated valve requirements.
Long Life Cycle
Bearings on all sliding and rotating moving parts to ensure long life.
Dual piston rack-and-pinion mechanism for simple construction, high cycle life, and constant torque.
Hard-anodized PTFE-coated extruded aluminum body with honed internal surface for strength and lower coefficient of friction.
Mechanically multi-guided aluminum pistons for precise movement, low friction, and high cycle life.
Machined teeth on piston racks and pinions for excellent rack and pinion engagement and maximum efficiency.
Corrosion Resistant
Hard-anodized PTFE-coated body, polyester-coated end caps, and epoxy-coated springs, along with internal and external stainless steel fasteners, provide corrosion resistance in a variety of difficult applications and environments.
Reliability
Safety-contained multi-spring design with preloaded and heavy-duty coated springs for simpler range versatility, greater safety, and corrosion resistance.
External adjustable stops in both directions assure flexibility and accuracy when setting the valve in the open and closed positions.
As an added safety feature, the external adjustment screws are designed to start venting internal pneumatic pressure in the actuator before the screw is fully backed out. The sound of escaping pressure indicates an unsafe condition.

- Jamesbury Quadra-Powr X 2(QPX2) including 60psi spring option and male square drive with 50 ft-lbs end of air output torque and 57 ft-lbs end of spring output torque at 60psi supply air. Jamesbury Part # C0221605 QPX2C/MC
Quadra-Powr X (QPX) Spring-Diaphragm Rotary ActuatorsExclusively developed for quarter-turn valve service, Quadra-PowrX spring-diaphragm actuators provide safe and reliable operation even when minimal supply pressures are available. Yet they are capable of operating at pressures as high as 7 bar (100 psi). These units can be operated by air, gas, water, oil, or other supply media compatible with the ductile iron/carbon steel casing of the actuator and the Buna-N diaphragm reinforced with polyamide fabric. Quadra-PowrX torque outputs range from 15 to 796 Nm (11 to 587 ft lbs), depending on actuator selection and available supply pressure.

Fail-Close Design &bull Dual Piston Rack-and-Pinion &bull Corrosion-Resistant Aluminum Body
The Jamesbury® VPVL200SR4/5BD Valv-Powr&trade Pneumatic Actuator (Part # MA0126197) delivers exceptional reliability and performance for automated valve control in industrial and process environments. Engineered for fail-close spring return operation, this actuator ensures safe, automatic closure when air pressure is lost&mdashideal for critical flow control systems requiring dependable safety measures.
With 13.0 ft-lbs of torque at 60 psi and 14.7 ft-lbs spring return torque, the VPVL200SR4/5BD provides smooth, consistent torque output thanks to its dual piston rack-and-pinion design. Bearings on all sliding and rotating parts minimize wear, while the PTFE-coated, hard-anodized aluminum body and epoxy-coated springs deliver outstanding corrosion resistance even in harsh conditions.
This actuator complies with ISO 5211 and NAMUR VDI/VDE 3845 standards for mounting and accessories, making it compatible with a wide range of ball, butterfly, and rotary valves. Its modular, field-convertible design allows for simple configuration changes between double-acting and spring-return models, offering flexibility across diverse applications.
Ideal for use in chemical plants, utilities, process automation, and OEM systems, the VPVL200SR4/5BD combines long service life, safety, and precise control in a compact, rugged package.

- Single-Source Responsibility• Valves, actuators, and accessories are designed to operate as a unit with the highest degree of compatibility. • Valves, actuators, and accessories can be supplied completely assembled to provide unit responsibility from a single source. Versatility• Modular designs with same body and end caps for double-acting and spring-return. Springs can be added in the field to convert double-acting to spring return or for changes in supply pressure. • Failure direction can be easily reversed from spring to-open or spring-to-close orientation simply by inverting the pistons. • Actuator to valve attachments comply with ISO 5211. • Solenoid valve and accessory attachments comply with NAMUR VDI/VDE 3845. • A wide range of optional accessories and control devices that include limit switches, solenoid valves, and mechanical safety lockouts are available to satisfy virtually all automated valve requirements.Long Life Cycle•Bearings on all sliding and rotating moving parts to ensure long life.•Dual piston rack-and-pinion mechanism for simple construction, high cycle life, and constant torque.•Hard-anodized PTFE-coated extruded aluminum body with honed internal surface for strength and lower coefficient of friction.•Mechanically multi-guided aluminum pistons for precise movement, low friction, and high cycle life.•Machined teeth on piston racks and pinions for excellent rack and pinion engagement and maximum efficiency.Corrosion Resistant•Hard-anodized PTFE-coated body, polyester-coated end caps, and epoxy-coated springs, along with internal and external stainless steel fasteners, provide corrosion resistance in a variety of difficult applications and environments. Reliability• Safety-contained multi-spring design with preloaded and heavy-duty coated springs for simpler range versatility, greater safety, and corrosion resistance.• External adjustable stops in both directions assure flexibility and accuracy when setting the valve in the open and closed positions.•As an added safety feature, the external adjustment screws are designed to start venting internal pneumatic pressure in the actuator before the screw is fully backed out. The sound of escaping pressure indicates an unsafe condition.:
