Power Generation Valves

CLASAR Check Valves

The blue, high-performance CLASAR valve delivers an ultra-fast dynamic response engineered specifically to shield power generation cooling loops and boiler feed lines from destructive water hammer events.

Designed for retrofitting into active plant infrastructure, this non-return check valve acts as a critical line of defense by sealing instantly before reverse fluid flow can create high-pressure shockwaves. Its robust, compact build minimizes fluid friction and stands up to demanding thermal and pressure environments, providing power plant engineers and procurement teams with a reliable solution to eliminate pipe fatigue, protect expensive turbine machinery, and prevent costly forced outages.

Dewrance

The Dewrance Valve range represents a legacy of robust engineering designed to deliver precise flow control and exceptional durability in the most demanding high-pressure fluid systems.

Valve specialists and spares have the capability to supply spare parts and technical support of all Dewrance spare parts for both current and past ranges. Whether maintaining modern equipment or sourcing obsolete components for legacy plant infrastructure, this specialized service ensures rapid access to precision-engineered trims, packings, and structural spares - providing procurement teams and maintenance engineers with the complete lifecycle support needed to extend asset lifespan, eliminate operational bottlenecks, and maintain strict plant compliance.

Hopkinsons

Valve Specialists and Spares supply spare parts and technical support for Hopkinson’s valves. If the valve is no longer manufactured VSAS can supply a suitable fully compliant valve of European manufacture in a reasonable time. Referrals are welcome.

Forged Gate Valve
Hopkinsons® has designed the Forged Gate Valve to provide assured, consistent, durable quality for high temperature and high pressure applications. Forged Gate Valves are the latest addition to the Hopkinsons® range. They offer customers choice across critical, super-critical, and ultra-super-critical steam applications.
Full Bore & Venturi Parallel Slide Gate
You would use these valves when you require a gate valve for steam or feedwater duty in medium and high pressure ranges.
FULL BORE
The outstanding feature of this parallel slide design is that of maintaining fluid-tightness without the aid of wedging action. Full bore valves exert no mechanical stress between the discs, and eliminate problems associated with cool-down of the fluid.
VENTURI
The Venturi design is used when a slightly higher pressure drop is acceptable. The well established principle of fluid flow through a Venturi minimises pressure drop. Venturi valves incorporate the design feature of an eye follower. In the fully open position the eye follower bridges the gap between the seats. This gives a smooth flow path and completes the Venturi profile.
Globe Valves
Hopkinsons® offers a robust general purpose range of globe valves suitable for regulating, isolating, and blowdown duties.
The replaceable seat is screwed into the body, the joint being made by accurately machined taper surfaces. An extension on the underside of the valve acts as a throttling device so as to protect the seating faces against the scoring or cutting action of steam during opening and closing.
High Performance Drain
For extreme service conditions such as on superheated steam drain lines, Hopkinsons® has developed a new range of high performance parallel slide gate valves.
Uniflow Slide Valve
Hopkinsons® designed the Uniflow Slide Valves for one way isolation and blowdown duties where there is no possibility of reversal flow.

Pilgrim Bolting

Delivering precision-engineered hydraulic bolting and drive solutions designed for high-load critical equipment. Engineered to eliminate installation friction and guarantee exact joint integrity, Pilgrim radial fit bolts and hydraulic nuts provide the reliable clamping force essential for heavy industrial machinery operating under extreme vibration and dynamic stress.

Maintaining exact shaft alignment and bolt tension in high-torque industrial environments is vital to preventing costly mechanical failures and downtime. Pilgrim bolting solutions utilize advanced hydraulic tensioning rather than traditional torque methods, ensuring uniform loading, zero thread friction, and rapid installation or removal during scheduled maintenance. From steam turbine couplings and power generation machinery to marine drive shafts and heavy industrial drives, Valve Specialists and Spares acts as your trusted supply partner for genuine Pilgrim components and spare parts - helping your facility achieve optimum joint performance, enhanced operational safety, and extended equipment lifespans.

Plenty

The heavy-duty Plenty fluid-handling and filtration range delivers precision process control engineered to maintain absolute system integrity and thermal efficiency in critical industrial environments.

While Valve Specialists and Spares (VSAS) focuses on delivering high-performance Plenty valves tailored for the power generation industry, the broader brand portfolio includes Plenty steam traps, simplex basket strainers, duplex basket strainers, and self-cleaning filters and strainers for use in a variety of industries including oil & gas, power, water & water treatment, food & beverage, edible oils. Through our specialized sourcing channels, power plant engineers and procurement teams can access these robust fluid-management technologies alongside core valve infrastructure—ensuring clean fluid lines, protecting downstream machinery, and preventing costly forced plant outages.

Richards Ball Valves

Richards Ball Valves - previously manufactured and supported by Tyco Australia. Richards Tyco Ball Valves have sadly ceased production.

Valve Specialists and Spares have the capability to supply the same design valve manufactured to the same face to face and BS 4504, 5351 and Australian drilling standards. We offer suitable replacement valves - hand leaver actuated or gear box mounted. We can supply the valve within a quick turnaround time for the DP ball valve range.

Tomoe

The high-performance Tomoe butterfly valve range delivers precision flow control and robust fluid isolation engineered specifically to withstand the extreme pressure and thermal cycles of power generation infrastructure.

The TOMOE range of Butterfly Valves is one of the finest and most comprehensive available, offering unparalleled levels of leak tightness, valve longevity and wear resistance. With an extensive range of body designs, material options and sizes, there is a TOMOE valve suitable for most applications. For power plant operators and procurement teams sourcing for cooling water loops, turbine systems, or low-pressure steam lines, these exceptionally engineered valves provide a reliable, bubble-tight sealing solution that minimizes frictional wear, extends maintenance intervals, and prevents costly operational downtime.

VSS Valves

The heavy-duty VSS valve range delivers specialized, high-integrity flow control and absolute fluid isolation engineered to withstand the most severe operating environments in power generation facilities.

Designed to meet the stringent demands of modern power plant infrastructure, the VSS portfolio covers an extensive array of critical-service designs, including:

• Ball Valves & Globe Valves: Optimized for extreme environments with High Pressure/Temperature ASME Class 900# – 4500# configurations.
• Bellow Seal & Cryogenic Valves: Engineered for zero-leakage packing preservation and extreme low-temperature fluid handling.
• Gate, Globe, Check, & Throttling Valves: Providing precise throttling, dependable backflow prevention, and reliable isolation.
• Parallel Slide & Butterfly Valves: Offering low-friction, high-endurance sealing mechanisms for high-velocity steam and water lines.

For sourcing managers and plant engineers, this comprehensive engineering capability ensures that whether you are replacing standard cooling loop infrastructure or retrofitting ultra-high-pressure boiler feed lines, VSS provides a robust, field-proven solution that ensures strict safety compliance and eliminates costly forced outages.
