Globe Valves

Hopkinsons offer 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 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 have developed a new range of high performance parallel slide gate valves.

Hopkinsons® High Performance Drains are designed to give extended service life and continued tight shut off when subject to frequent operation, two phase flow, thermal shock and large pressure drops. Unique features of the valves include square discs (gates) and 'winged' seats. These provide accurate gate guidance, low seat contact stresses and enhanced wear resistance for repeatedly handling large pressure drops in the part open position.

Full Bore & Venturi Parallel Slide Gate

We recommend Hopkinsons Full Bore & Venturi valves when a gate valve is required for steam or feedwater duty in medium and high pressure ranges.

Full Bore: The outstanding feature of the parallel slide design is that of maintaining fluid-tightness without the aid of wedging action. No mechanical stress is exerted between the discs, and there are no problems associated with cool-down of the fluid.

BV994 & BV995 Turbine Bypass Valves

The BV994/995 is an innovative product designed for power customers to combine steam pressure reducing and desuperheating stations.

The Trillium BV994/BV995 Turbine Bypass Valve is a highly sophisticated engineered control device. Conceptually, it is required to accurately control multiple operational variables, provide system protection to both upstream and downstream plant components, and sometimes perform these tasks all in a fraction of a second. Depending on the overall system size, bypass mode of operation and customer preference, there is almost an endless selection of options and configurations that can be applied to the BV995 bypass valve construction. The Weir BV995 Turbine Bypass Valve design can be varied to accommodate the particular plant design, size, and application. It is available in a range of options and configurations to assure optimum performance regardless of the mode of operation. The high pressure (HP) bypass valves are subject to some of the highest pressures and temperatures. They may be utilized in either a Parallel or Cascading Bypass System.

BV986 Desuperheater

The BV986 desuperheater is designed as a compact solution suitable for steam conditioning applications for pipe sizes up to 6".

This BV986 unit offers a relatively simple and inexpensive solution for applications which have low rangeability and stable steam demand. The unit is a simplified spray nozzle where the spray water is circulated around an internal gallery and then injected into the steam through a series of radial holes. The BV986 unit also fits between conventional flanges and is therefore easy to remove for service and maintenance purposes. The unit is connected to a stand-alone spray water valve which controls the amount of water being injected into the vapour. The BV986 can also be directly mounted onto the outlet of a pressure control valve so that water is injected into the turbulent vapour flow at the outlet of the valve. The BV986 desuperheater is used on pipe sizes from 25mm (1"") and above.

BV985 Desuperheater

Our multi-nozzle desuperheater design is proven in thousands of installations. The BV985 offers increased CV ratings and improved rangeability with options of modified characteristics.

The BV985 spray nozzle is used on applications where high rangeability is required with direct control across the spray nozzle. The BV985 is designed so that steam is injected into the centre of the pipe resulting in minimum droplet contact against the pipe walls. Water is injected across a series of 12 variable area nozzles which atomises the water into micro fine droplets resulting in faster absorption rates and shorter outlet steam pipe lengths. The amount of water injected into the pipe is directly controlled by the valve plug which is in turn controlled by the actuator. Where the pressure differential between the cooling medium and the vapour exceeds 60 bar, a two stage nozzle is available that extends the available pressure drop range to 100 bar. The two stage nozzle ensures erosion across the valve plug is minimised.

BV830 & BV831 Three Way Valves

The Blakeborough BV830/831 series are popular top and skirt guided control valves available to customers in a variety of trims, capacities, and options.

The BV830 and BV831 valves are designed for either blending two different flows or for dividing a flow into two proportional streams. The valves can be used on a wide variety of process applications, including air, water, steam, oil, gases and chemical services. The BV830 has two inlets and a common outlet branch. It is used for proportional blending of two flows into one stream, on such applications as the control of process fluid temperature downstream of feedwater heaters. The valve can also be used as a mixing valve to control the blending of two flow streams. The flow capacity is normally constant unless the valve trim is specifically designed with two different CVs. The BV831 valves are used for proportional control on flow splitting applications. The valve has two outlets and a common inlet branch.

X-Stream trim for severe services

X-Stream represents the state of the art in severe service trim. Innovative design and engineering techniques enabled us to deliver a multi stage trim for severe service applications.

The Blakeborough® X-Stream™ represents the state of the art in severe service trim. Combining different velocity control methods it eliminates at the root problems related to cavitation, erosion, noise or vibration. The concept derives from intuition refined by sophisticated simulation techniques and it's validated by accurate testing and hundreds of installations. Its design develops the traditional concept of disk stack multistage trim to its maximum potential combining the effect of three different methods of velocity reduction. At the same time it minimises risk of blockage in case of solids and achieves high capacity resulting in compact dimensions. X-stream™ is the only trim that ensures Total Velocity Control: fluid velocity is not limited only at trim exit but throughout the flow path.

BV 34000 Vulcanised rubber lined

Vulcanised rubber lined butterfly valves developed to address a high quality, low cost valve, for use on corrosive line fluids such as seawater and brine.

The Batley Valve® BV 34000 vulcanised rubber lined butterfly valve incorporates a liner that is bonded to the valve body. This allows the valve to have higher closed differential pressures from full vacuum up to 20 bar g and the potential for higher fluid velocities up to 8 metres per second (dependent on valve size). The valve body incorporates a small raised spigot that prevents the body liner from being over compressed during installation.

BV 32000 Refractory lined

The BV 32000 - Refractory lined is designed for temperatures above 1000C, or where higher pressures are involved, such as a water cooled design.

Experience of Refractory Lined Valves has been for gases at temperatures up to 1200ºC with low or negligible pressure. Materials of construction can vary considerably depending upon temperature, pressure, temperature fluctuation, flowing media, particularly in respect to oxidising or sulphurous atmospheres and clients own specifications. We recommend that the refractory cement lining is accurately cast into the body in our works to avoid problems on-site or in service.
